Clarify RAM usage during build in README

The sentence wasn't immediately clear if it meant RAM or disk space before reading the next sentence.

I think this helps clarify it.

Update grammar to parse current rust syntax

Mainly addressing . This PR updates the bison grammar so that it can parse the current rust syntax, except for feature-gated syntax additions. It has been tested with all the tests in run-pass.

The grammar in this repo doesn't have build logic anymore, but you can test it out in https://github.com/bleibig/rust-grammar, which has all of what's in this PR. If you are interested in having build logic and grammar tests again, I can look into implementing that as well.

I'm aware that things are somewhat undecided as to what an official rust grammar should be from the discussion in . With this PR we can go back to having an up-to-date flex/bison based grammar, but the rustypop grammar looks interesting as well.

Rollup merge of - johnthagen:none-identity-test, r=sfackler
Use identity operator `is` when comparing to None

This is very minor, but idiomatic Python code uses `is` for comparisons to `None`. This is because semantically we want to compare to the "identity" of `None`, not its value.

See [PEP8 for details](https://www.python.org/dev/peps/pep-0008/#programming-recommendations).

Fix raising a bare str as an exception in configure.py

Raising a bare `str` has been [deprecated since Python 2.5](https://docs.python.org/2/whatsnew/2.5.html#pep-352-exceptions-as-new-style-classes).

On Python 2.7 it produces the following error:

```
TypeError: exceptions must be old-style classes or derived from BaseException, not str
```

For maximum compatibility with Python 2.7 and 3.x, we wrap the error message in `RuntimeError` which derives from `Exception`.

rustc: Don't inline in CGUs at -O0

This commit tweaks the behavior of inlining functions into multiple codegen
units when rustc is compiling in debug mode. Today rustc will unconditionally
treat `#[inline]` functions by translating them into all codegen units that
they're needed within, marking the linkage as `internal`. This commit changes
the behavior so that in debug mode (compiling at `-O0`) rustc will instead only
translate `#[inline]` functions into *one* codegen unit, forcing all other
codegen units to reference this one copy.

The goal here is to improve debug compile times by reducing the amount of
translation that happens on behalf of multiple codegen units. It was discovered
in  that increasing the number of codegen units had the adverse side
effect of increasing the overal work done by the compiler, and the suspicion
here was that the compiler was inlining, translating, and codegen'ing more
functions with more codegen units (for example `String` would be basically
inlined into all codegen units if used). The strategy in this commit should
reduce the cost of `#[inline]` functions to being equivalent to one codegen
unit, which is only translating and codegen'ing inline functions once.

Collected [data] shows that this does indeed improve the situation from [before]
as the overall cpu-clock time increases at a much slower rate and when pinned to
one core rustc does not consume significantly more wall clock time than with one
codegen unit.

One caveat of this commit is that the symbol names for inlined functions that
are only translated once needed some slight tweaking. These inline functions
could be translated into multiple crates and we need to make sure the symbols
don't collideA so the crate name/disambiguator is mixed in to the symbol name
hash in these situations.

Remove support for the PNaCl target (le32-unknown-nacl)

This removes support for the `le32-unknown-nacl` target which is currently supported by rustc on tier 3. Despite the "nacl" in the name, the target doesn't output native code (x86, ARM, MIPS), instead it outputs binaries in the PNaCl format.

There are two reasons for the removal:

* Google [has announced](https://blog.chromium.org/2017/05/goodbye-pnacl-hello-webassembly.html) deprecation of the PNaCl format. The suggestion is to migrate to wasm. Happens we already have a wasm backend!
* Our PNaCl LLVM backend is provided by the fastcomp patch set that the LLVM fork used by rustc contains in addition to vanilla LLVM (`src/llvm/lib/Target/JSBackend/NaCl`). Upstream LLVM doesn't have PNaCl support. Removing PNaCl support will enable us to move away from fastcomp () and have a lighter set of patches on top of upstream LLVM inside our LLVM fork. This will help distribution packagers of Rust.

MIR-borrowck: gather and signal any move errors

When building up the `MoveData` structure for a given MIR, also accumulate any erroneous actions, and then report all of those errors when the construction is complete.

This PR adds a host of move-related error constructor methods to `trait BorrowckErrors`. I think I got the notes right; but we should plan to audit all of the notes before turning MIR-borrowck on by default.

Add -Zmutable-noalias flag

We disabled noalias on mutable references a long time ago when it was clear that llvm was incorrectly handling this in relation to unwinding edges.

Since then, a few things have happened:

* llvm has cleaned up a bunch of the issues (I'm told)
* we've added a nounwind codegen option

As such, I would like to add this -Z flag so that we can evaluate if the codegen bugs still exist, and if this significantly affects the codegen of different projects, with an eye towards permanently re-enabling it (or at least making it a stable option).

enable strict alignment (+strict-align) on ARMv6

As discovered in  ARMv6 devices may or may not support unaligned memory accesses. ARMv6
Linux *seems* to have no problem with unaligned accesses but this is because the kernel is stepping
in to fix each unaligned memory access -- this incurs in a performance penalty.

This commit enforces aligned memory accesses on all our in-tree ARM targets that may be used with
ARMv6 devices. This should improve performance of Rust programs on ARMv6 devices. For the record,
clang also applies this attribute when targeting ARMv6 devices that are not running Darwin or
NetBSD.
