Evan Cheng 3b0f5e4d61 - Add target lowering hooks that specify which setcc conditions are illegal, ... i.e. conditions that cannot be checked with a single instruction. For example, SETONE and SETUEQ on x86. - Teach legalizer to implement *illegal* setcc as a and / or of a number of legal setcc nodes. For now, only implement FP conditions. e.g. SETONE is implemented as SETO & SETNE, SETUEQ is SETUO | SETEQ. - Move x86 target over. llvm-svn: 57542		2008-10-15 02:05:31 +00:00
