6097f82e18 simplify fast isel by using ClassifyGlobalReference. This 
elimiantes the last use of GVRequiresExtraLoad, so delete it.

need for other purposes.

e4e0c73ed0 change a bunch of logic in LowerGlobalAddress to leverage the work 
done in ClassifyGlobalReference instead of reconstructing the info
awkwardly.

a785e01d31 add a predicate to determine if a global var reference requires a 
PIC-base to be added in.

0cae8c7845 move some classification logic around. Now GVRequiresExtraLoad 
is just a trivial wrapper around "ClassifyGlobalReference", which
stole a ton of logic from LowerGlobalAddress.

c4e0e9c987 convert some late code (called by regalloc and code emission) 
to use isGlobalStubReference instead of GVRequiresExtraLoad
(which should really be part of isel).

a607a9c046 add a new predicate method that says whether a GlobalValue 
MachineOperand is a reference to a stub, not a reference to the
global variable itself.  Look no context needed!

832a724072 actually, just eliminate PCRelGVRequiresExtraLoad. It makes the code 
more complex and slow than just directly testing what we care about.

based on this.

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)!!!

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.

cd52f7f20e When in -static mode, force the PIC style to none. Doing this requires fixing 
code which conflated RIPRel PIC with x86-64.  Fix these to just check for X86-64
directly.
