Relax expressions and add explicit triplets -linux and -win32. llvm-svn: 126201

Add the ExceptionHandling::MSVC enumeration It is intended to be used for a family of personality functions that have similar IR preparation requirements. Typically when interoperating with MSVC personality functions, bits of functionality need to be outlined from the main function into helper functions. There is also usually more than one landing pad per invoke, which does not match the LLVM IR landingpad representation. None of this is implemented yet. This change just adds a new enum that is active for *-windows-msvc and delegates to the EH removal preparation pass. No functionality change for other targets. llvm-svn: 224625

Fix x86 fast-isel's cmp+branch folding to avoid folding when the comparison is in a different basic block from the branch. In such cases, the comparison's operands may not have initialized virtual registers available. llvm-svn: 111709

; Fast-isel shouldn't try to look through the compare because it's in a
; different basic block, so its operands aren't necessarily exported
; for cross-block usage.

Move the personality function from LandingPadInst to Function The personality routine currently lives in the LandingPadInst. This isn't desirable because: - All LandingPadInsts in the same function must have the same personality routine. This means that each LandingPadInst beyond the first has an operand which produces no additional information. - There is ongoing work to introduce EH IR constructs other than LandingPadInst. Moving the personality routine off of any one particular Instruction and onto the parent function seems a lot better than have N different places a personality function can sneak onto an exceptional function.
