area to avoid using up precious stack space within the 4095 offset limit
from %fp.  Such objects that would themselves live at a large offset
were being put there already so this is a simple change.

    deletes it, but we were merrily trying to fix the operands of that
    instruction anyway!  Instead, fix the replacement instruction.

(2) An Improvement: Check for and extract global values in all operands,
    not just in known pointer operands.  For example, they can occur in
    call arguments, and probably other unforeseeable places as well.
    This also eliminates the special-case handling of Load and Store.

not just an Instruction*, at least in one unfortunate case:
the first operand to the va_arg instruction.
Modify ValueToDefVecMap to map from Value*, not Instruction*.

(1) select: Ok to convert a pointer to a float or double.
(2) regalloc: Some MachineInstr* for caller-saving code before a call
    were being inserted before and after the call!
(3) Don't insert the caller-saving instructions in the
    MachineCodeForInstruction for the Call instruction.
    *All* instructions generated by register allocation need to be
    recorded in those maps, but it needs to be done uniformly.

and keeps some of the test Makefiles from breaking.

One of the test Makefiles uses the same variable names for something else,
and this was probably interfering with it.
