26b6c0ba5d On Mac OS/X, make Process::PreventCoreFiles disable crash reporter for 
the process in addition to disabling core file emission.  This speeds up
bugpoint on default-configured macs by several orders of magnitude.

c970f062e0 If LSR went through a lot of trouble to put constants (e.g. the addr of a global 
in a specific BB, don't undo this!).  This allows us to compile
CodeGen/X86/loop-hoist.ll into:

_foo:
        xorl %eax, %eax
***     movl L_Arr$non_lazy_ptr, %ecx
        movl 4(%esp), %edx
LBB1_1: #cond_true
        movl %eax, (%ecx,%eax,4)
        incl %eax
        cmpl %edx, %eax
        jne LBB1_1      #cond_true
LBB1_2: #return
        ret

instead of:

_foo:
        xorl %eax, %eax
        movl 4(%esp), %ecx
LBB1_1: #cond_true
***     movl L_Arr$non_lazy_ptr, %edx
        movl %eax, (%edx,%eax,4)
        incl %eax
        cmpl %ecx, %eax
        jne LBB1_1      #cond_true
LBB1_2: #return
        ret

This was noticed in 464.h264ref.  This doesn't usually affect PPC,
but strikes X86 all the time.

        movl 8(%esp), %ecx
        leal -5(%ecx,%eax,4), %eax

instead of:

_test:
        movl 4(%esp), %eax
        leal (,%eax,4), %eax
        addl 8(%esp), %eax
        addl $4294967291, %eax

c66764c007 This code was trying too hard. By eliminating redundant edges in the CFG

dc08cd56c4 Replace EquivalenceClasses with a custom-built data structure. Many common
