Currently not, because this patch lets gas parse %higher and %highest,
but actually using this requires handling of R_MIPS_HIGHER and
R_MIPS_HIGHEST relocations which is not available in gas yet.
On the other hand, the easiest way to test these relocations is via
%higher and %highest.
On the third hand, too large patches are a bad thing.

I plan to add testcases together with the relocation support.
