[Intel-gfx] [PATCH i-g-t] tests: Fix compilation when some gcc configurations

[Damien Lespiau]

Depending how the gcc was compiled it may be necessary to enable SSE4
instructions explicitly. Otherwise:

  CC       gem_gtt_speed.o
In file included from gem_gtt_speed.c:54:0:
/usr/lib/gcc/x86_64-linux-gnu/4.8/include/smmintrin.h:31:3: error: #error "SSE4.1 instruction set not enabled"
 # error "SSE4.1 instruction set not enabled"
   ^

v2: Use a pragma directive (Chris)
