This change adds --soft-float option for generating
software floating point library calls.
It also implies using soft float ABI, that is the same as llc.
It is useful for targets that have no FPU.
We're not outright removing fmt! just yet, but this prevents it from leaking
into the compiler further (it's still turned on by default for all other code).

This is mostly an incremental change, picking off some uses of
@- or @mut-pointers that can be replaced by references.
Almost all of the builder functions in trans::build are updated,
mostly using `&Block` arguments instead of `@mut Block`.
Use &mut Block and &Block references where possible in the builder
functions in trans::build.
@mut Block remains in a few functions where I could not (not yet at
least) track down the runtime borrowck failures.
This patch exposes actual ownership of an `ast::Crate` structure so it's not implicitly copied and reference counted via `@`.
The main purpose for this patch was to get rid of the massive spike in memory during the start of the compiler (this can be seen on isrustfastyet). The reason that this spike exists is that during `phase_2` we're creating many copies of the crate by folding. Because these are reference counted, all instances of the old crates aren't dropped until the end of the function, which is why so much memory is accumulated.
This patch exposes true ownership of the crate, meaning that it will be destroyed ASAP when requested. There are no code changes except for dealing with actual ownership of the crate. The large spike is then avoided: http://i.imgur.com/IO3NENy.png
This shouldn't help our overall memory usage (that still is the highest at the end), but if we ever manage to bring that down it should help us not have a 1GB spike at the beginning of compilation.
(This was to un-stuck bors (hopefully).)
Previously, if tests failed, you'd only get stderr which isn't very
useful, especially if the failure didn't happen directly in a test
function (e.g None.unwrap()).
