38b0644761 Revert the part of 75177 that split ConstantRange into two classes, and
merge the new functionality and unittests into ConstantRange. Thanks to
Nick Lewycky for pointing out that it isn't necessary to have two separate
classes here.

d15f45f53e 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)!!!

a3755d8d36 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.

c680ac9003 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.

3a780d1214 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.

910139f9ca 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.
