[jsc][mips] fix JIT::emit_op_log_shadow_chicken_prologue/_tail
https://bugs.webkit.org/show_bug.cgi?id=158209
Patch by Guillaume Emont <[email protected]> on 2016-06-06
Reviewed by Mark Lam.
On MIPS, changes GPRInfo::nonArgGPR0 to be regT4 instead of regT0,
since the code of JIT::emit_op_log_shadow_chicken_prologue/_tail()
expects nonArgGPR0 to be a different register from regT0 and regT2.
* jit/GPRInfo.h:
