If -fomit-frame-pointer is used, we still need to record when the %esp register

started my hacking) did this. It dropped on the floor, because I wasn't aware of
this requirement.

On the plus side, if we use "alloca" in a function, we create frame pointers

There's no need to consider PHI nodes in the same block as the instruction
we're inserting sigma/phi functions for. Patch by Andre Tavares.

Add a -t="dir" option to the driver. This can be used to specify the directory to be used as TempDir if somebody doesn't want to use the standard /tmp.

isel.

Targets sometimes assign fixed stack object to spill certain callee-saved
registers based on dynamic conditions. For example, X86 EBP/RBP, when used as
frame register has to be spilled in the first fixed object. It should inform
PEI this so it doesn't get allocated another stack object. Also, it should not
be spilled as other callee-saved registers but rather its spilling and restoring
are being handled by emitPrologue and emitEpilogue. Avoid spilling it twice.
