bea3f096ee Add support for arbitrary metadata for numbers and widths. 
This means that each platform has total control over the formatting info
it needs.

73811917f4 Add the platform intrinsic generator script. 
This python script will consume an appropriately formatted JSON file and
output either a Rust file for use in librustc_platform_intrinsics, or an
extern block for importing the intrinsics in an external library.

The --help flag has details.

72382d247a Avoid eagerly stripping the common platform prefix. 
This works better with the code generation approach.

ee2de27996 Add support for aggregates in platform intrinsics. 
This adds support for flattened intrinsics, which are called in Rust
with tuples but in LLVM without them (e.g. `foo((a, b))` becomes `foo(a,
b)`). Unflattened ones could be supported, but are not yet.

b03ca7f805 Separate integers into signed and unsigned. 
This is necessary to reflect the ARM APIs accurately, since some
functions explicitly take an unsigned parameter and a signed one, of the
same integer shape, so the no-duplicates check will fail unless we
distinguish.

f578735750 Tweak aarch64 SIMD intrinsics. 
The definitions of the rsqrte and recpe had typos, and vqtbl1q is useful
for a benchmark (fannkuch-redux).

everywhere.

891c91438d simd_shuffleNNN returns its type parameter directly. 
I.e. the signature now must be

    fn simd_shuffleNNN<T, U>(x: T, y: T, idx: [u32; NNN]) -> U;

(modulo names.)

d792925b4d Shim some of the old std::simd functionality. 
Overload the operators using the traits so that things mostly keep
working during the deprecation period.

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.

c66554cab3 switch core::simd to repr(simd) and deprecate it.

crates.io.
