Subject: [PATCH 1/2] Add _MM_FROUND_TIES_TO_EVEN to avx512fintrin.h
Intrinsics such as `_mm512_add_round_ps` take a rounding mode argument to
specify the floating point rounding mode. This, and similar instructions, do
NOT round their result to an integer. Thus it is inappropriate for user code
to specify the existing `_MM_FROUND_TO_NEAREST_INT` when desiring to round to
the nearest floating point number. This commit adds a suitable macro
definition.
