bors 471862f40c auto merge of #16710 : dotdash/rust/mergefunc, r=thestinger
Fixes #9536 

---

From https://github.com/rust-lang/rust/issues/9536#issuecomment-45495670:

I've built rustc with the aforementioned fix, once with MergeFunc being run early (that's what the patch for clang that comes  with LLVM does), and once with MergeFunc being run late (using `-C passes=mergefunc`). Here are some time/code size measurements I made with them:

Build command: `rustc -O -o /dev/null --emit asm .../lib.rs`

CPU (user) times, best of three runs:

So running MergeFunc early like in the clang patch isn't nearly as good as running it late. I also tried to enable usage of global aliases instead of just thunks when merging functions, but that crashes.

These are somewhat stop-gap solutions to address #16625 

core: Separate failure formatting in str methods slice, slice_to, slice_from

Use a separate inline-never function to format failure message for
str::slice() errors.

Using strcat's idea, this makes sure no formatting code from failure is
inlined when str::slice() is inlined. The number of `unreachable` being
inlined when usingi `.slice()` drops from 5 to just 1.



The testcase:

```
#![crate_type = "lib"]
pub fn slice(x: &str, a: uint, b: uint) -> &str {
    x.slice(a, b)
}
```

shrinks from 16.9 kB to 3.3 kB llvm IR, and the number of `unreachable` drops from 5 to 1.

I was doing a lot of parsing ascii strings, and the generic bsearch functions in `tables.rs` came up very high in the profile.
This should avoid calling those functions for simple ASCII range chars.

bors 03fd90be45 auto merge of #16612 : nham/rust/twoway_searcher_fix, r=alexcrichton
There is a check in TwoWaySearcher::new to determine whether the needle is periodic. This is needed because during searching when a match fails, we cannot advance the position by the entire length of the needle when it is periodic, but can only advance by the length of the period.

The reason "bananas".contains("nana") (and similar searches) were returning false was because the periodicity check was wrong.

Closes #16589

Also, thanks to @Gankro, who came up with many buggy examples.

Use a separate inline-never function to format failure message for
str::slice() errors.

Using strcat's idea, this makes sure no formatting code from failure is
inlined when str::slice() is inlined. The number of `unreachable` being
inlined when usingi `.slice()` drops from 5 to just 1.

klutzy 7eb35bc2a9 test: Convert Window path to MSYS path
When MSYS shell executes program, if its arguments look like MSYS paths,
MSYS automatically converts them into Windows paths.
For example, `/c/path:/d/path` becomes `C:\path;D:\path`.
However, if there is only one path e.g. `/c/path`, it becomes `C:/path`.

maketest.py reverts the behavior to reduce confusion between MSYS and
Windows, but it didn't handle the `/c/path` case. This patch fixes the
issue.
