[MIPS] Use btpz to compare against 0 instead of bpeq
https://bugs.webkit.org/show_bug.cgi?id=185607
Patch by Dominik Infuehr <dinfu...@igalia.com> on 2018-05-14
Reviewed by Yusuke Suzuki.
Fixes build on MIPS since MIPS doesn't have an instruction to
compare a register against an immediate. Since the immediate is just 0
in this case the simplest solution is just to use btpz instead of bpeq
to compare to 0.
