[X86] Use update_llc_test_checks.py to regenerate a test. llvm-svn: 298044

[X86][FastISel] Use a COPY from K register to a GPR instead of a K operation The KORTEST was introduced due to a bug where a TEST instruction used a K register. but, turns out that the opposite case of KORTEST using a GPR is now happening The change removes the KORTEST flow and adds a COPY instruction from the K reg to a GPR.

[X86][AVX512] Make i1 illegal in the CodeGen This patch defines the i1 type as illegal in the X86 backend for AVX512. For DAG operations on <N x i1> types (build vector, extract vector element, ...) i8 is used, and should be truncated/extended. This should produce better scalar code for i1 types since GPRs will be used instead of mask registers. Differential Revision: https://reviews.llvm.org/D32273 llvm-svn: 303421
