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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57542 91177308-0d34-0410-b5e6-96231b3b80d8
