[MIPS] signal: clean up sigframe structure
This patch makes 'struct sigframe' declaration avalaible for all signals
code. It allows signal32 to not have its own declaration.
This patch also removes all ICACHE_REFILLS_WORKAROUND_WAR tests in
structure declaration and hopefully make them more readable.
