717da9513f Create "platform-intrinsic" ABI for SIMD/platform intrinsics. 
This is purposely separate to the "rust-intrinsic" ABI, because these
intrinsics are theoretically going to become stable, and should be fine
to be independent of the compiler/language internals since they're
intimately to the platform.

e364f0eb5a feature gate cfg(target_feature). 
This is theoretically a breaking change, but GitHub search turns up no
uses of it, and most non-built-in cfg's are passed via cargo features,
which look like `feature = "..."`, and hence can't overlap.

8cb4d8671a std: Clean up primitive integer modules

in libcore, so remove all the "macro modules" from the standard library and just
reexport what's in core directly.

bfc45834c1 test: Don't panic if some tests failed 
This commit removes the call to `panic!("Some tests failed")` at the end of all
tests run when running with libtest. The panic is replaced with
`std::process::exit` to have a nonzero error code, but this change both:

1. Makes the test runner no longer print out the extraneous panic message at the
   end of a failing test run that some tests failed. (this is already summarized
   in the output of the test run).
2. When running tests with `RUST_BACKTRACE` set it removes an extraneous
   backtrace from the output (only failing tests will have their backtraces in
   the output.

96e6b2fef8 use an FnvHashSet instead of an HashSet in fulfill 
this doesn't cause a measurable perf increase, but it makes callgrind output
cleaner. Anyway, rustc should be using FNV everywhere.

1ddee8070d Remove dependencies on libm functions from libcore. 
There wasn't any particular reason the functions needed to be there
anyway, so just get rid of them, and adjust libstd to compensate.

With this change, libcore depends on exactly two floating-point functions:
fmod and fmodf.  They are implicitly referenced because they are
used to implement "%".
