This fixes a build failure on MSVC.
BTW, it looks like clang supports _Pragma() but I don't know if it
understands the "gcc unroll N" directive.
It probably doesn't, but that should be okay. This just exists to speed
up the debug builds in the pre-merge CI.

BTW, With gcc 5.4.0, there's a lot of warnings about the pragma not
being understood:
../src/compiler/nir/nir_range_analysis.c:268:0: warning: ignoring
#pragma GCC unroll [-Wunknown-pragmas]
ASSERT_TABLE_IS_COMMUTATIVE(union_table);
^
../src/compiler/nir/nir_range_analysis.c:268:0: warning: ignoring
#pragma GCC unroll [-Wunknown-pragmas]
../src/compiler/nir/nir_range_analysis.c:269:0: warning: ignoring
#pragma GCC unroll [-Wunknown-pragmas]
I'd have to dig to see what version of gcc added that to add more
preprocessor tests to silence it.
