microMIPS/GAS: Handle several percent-ops with macros
In the microMIPS mode also accept %half, %got, %call, %got_hi, %got_lo,
%call_hi, %call_lo, %neg, %got_page, %highest, %got_disp, %tlsgd,
%tlsldm, %dtprel_hi, %dtprel_lo, %gottprel, %tprel_hi and %tprel_lo
percent-ops with macros, so that they can be used with instructions that
expand into sequences if relocation is required due to their limited
offset span, such as LL, LWL, etc., fixing GAS assertions:
