using our broad selection of movcc instructions.  :)

max:
        mov %EAX, DWORD PTR [%ESP + 4]
        mov %ECX, DWORD PTR [%ESP + 8]
        cmp %EAX, %ECX
        cmovle %EAX, %ECX
        ret

Someone should really implement passing arguments through registers for
known-internal functions.  :)

pass can eliminate many nasty cases of them, start generating them in the optimizers

an incoming value from a block, the selector would evaluate the constant
at the TOP of the block instead of at the end of the block.  This made the
live range for the constant span the entire block, increasing register
pressure needlessly.

Otherwise, if you're in debugging mode, you get warnings for (apparently)
every immediate constant in the function during reg. allocation.

#1 is to unconditionally strip constantpointerrefs out of
instruction operands where they are absolutely pointless and inhibit
optimization.  GRRR!

#2 is to implement InstCombine/getelementptr_const.ll
