Craig Topper dfc4fc9f02 [AVX-512] Teach fastisel load/store handling to use EVEX encoded instructions for 128/256-bit vectors and scalar single/double. 
Still need to fix the register classes to allow the extended range of registers.

Craig Topper 70e1348031 [X86] Update fast-isel store test to have more 256 and 512-bit test cases. Add command lines for AVX and AVX512 feature sets.

Mehdi Amini 945a660cbc Change the fast-isel-abort option from bool to int to enable "levels" 
Summary:
Currently fast-isel-abort will only abort for regular instructions,
and just warn for function calls, terminators, function arguments.
There is already fast-isel-abort-args but nothing for calls and
terminators.

This change turns the fast-isel-abort options into an integer option,
so that multiple levels of strictness can be defined.
This will help no being surprised when the "abort" option indeed does
not abort, and enables the possibility to write test that verifies
that no intrinsics are forgotten by fast-isel.
