Various extensions to the vectorizer
Includes additions to the AstVectorizer:
- Vectorize assignments to vector symbols
- Vectorize loops nested within the vectorization axis if all bounds are independent of the axis
- Vectorize array subscripts if all indices and the array expression are independent of the axis
- Handle empty nodes (e.g. comments)
Additions to the x86 instruction set:
- Intrinsics for basic math functions (log, abs, etc.)
- Type conversions
And to the SelectIntrinsics pass:
- Add option to implemenet type conversions using
__builtin_convertvectorwhich is supported by most compilers instead of inserting intrinsics. Useful because not all conversions are supported natively on all CPUs.

- 8b8d5534 - Extend test_functions to use vector targets when available. Add tests for integer min/max/abs.
- Resolved by Daniel Bauer
I just pushed the extension to the functions test suite, as discussed. In addition, we still need tests for the type casts and vector conversions.

One problem the latest pipeline detected is that
_mm_loadu_epi32and_mm_storeu_epi32(128bit versions) are AVX512 instructions. - Last reply by Daniel Bauer
