    Allow multiple terminators to read virtual registers.

    Ensure CopyToReg nodes are always glued to the call instruction.

    stoklund authored
    The CopyToReg nodes that set up the argument registers before a call
    must be glued to the call instruction. Otherwise, the scheduler may emit
    the physreg copies long before the call, causing long live ranges for
    the fixed registers.
    
    Besides disabling good register allocation, that can also expose
    problems when EmitInstrWithCustomInserter() splits a basic block during
    the live range of a physreg.

    Add early if-conversion support to X86.

  13. @stoklund

    Add an experimental early if-conversion pass, off by default.

    stoklund authored
    This pass performs if-conversion on SSA form machine code by
    speculatively executing both sides of the branch and using a cmov
    instruction to select the result. This can help lower the number of
    branch mispredictions on architectures like x86 that don't have
    predicable instructions.
    
    The current implementation is very aggressive, and causes regressions on
    mosts tests. It needs good heuristics that have yet to be implemented.
