Add ISA annotations to functions using SIMD, AES, etc
Also emit `#pragma GCC target` in the ISA specific amalgamation files.
This allows compiling without any special compiler flags, at least
with GCC 6.2 and Clang 3.8. The ISA annotations are ignored in MSVC,
which just emits whatever instruction the intrinsic requires.
