Subject: [PATCH] util: Do not include immintrin.h in half_float.h
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

The files included are extremely large and hurt compile time of
everything that inludes half_float.h directly or indirectly.

Compile time of a fresh RADV build:
before 32.477s 32.661s 32.625s
after  25.116s 24.928s 25.114s

v2: Include xmmintrin instead (Marek Olšák)
after  25.552s 25.811s 25.678s
