4b9c615e09 If -fomit-frame-pointer is used, we still need to record when the %esp register 
is modified. Otherwise, the unwinder will get confused. The old code (before I
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
even with -fomit-frame-pointer is enabled!

This is a Good Thing(tm)!!!

3b7c3fafab Fix ldrd / strd address mode matching code. It allows for +/- 8 bit offset. Also change the printer to make the scale 4 explicit. 
Note, we are not yet generating these instructions.

33251eff97 Add a ConstantSignedRange class, which does for signed integers 
what ConstantRange does for unsigned integers. Factor out a
common base class for common functionality.

Add some new functions for performing arithmetic on constant
ranges. Some of these are currently just stubbed out with
conservative implementations.

Add unittests for ConstantRange and ConstantSignedRange.

08991c716a Make EXTRACT_VECTOR_ELT a bit more flexible in terms of the returned 
value.  Adjust other code to deal with that correctly.  Make 
DAGTypeLegalizer::PromoteIntRes_EXTRACT_VECTOR_ELT take advantage of 
this new flexibility to simplify the code and make it deal with unusual 
vectors (like <4 x i1>) correctly.  Fixes PR3037.

1958523090 Rename -t to --temp-dir. 
-t is already used by gcc in the meaning 'ld -t' (trace). The Base plugin may
 want to emulate this behaviour.

4f87295872 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.
