5548609204 Add const unstability attributes 
These are needed for rustc to be able to correctly handle stability of constness of intrinsics. Without either `rustc_const_unstable` or `rustc_const_stable` an intrinsic is not const evaluable at all.

c8249c76c4 Revert mmx changes 
On i586 the simd_* intrinsics don't compile to MMX instructions, even
with `#[target_feature(enable = "mmx")]`.

cca9a86637 Add CRC32 detection to arm32 
armv8 has 32-bit mode, but it can use crc32 instruction sets even if 32-bit.

f3140f4b25 Factor out check_for 
All the os-specific code implements a `check_for` and a `detect_features`.

Move the always identical check_for in the mod.rs and use
`os::detect_features` there.
