d3ec0b5446 eliminate the GVStubs and HiddenGVStubs maps, and use 
MachineModuleInfoMachO instead.  This eliminates two sources
of nondeterministic output in the ppc backend, but function
stubs are still bad.

described in PR6019.

d8d0b6a42c When doing address-mode sinking, expand the base register first, rather 
than the scaled register. This makes it more likely that subsequent
AddrModeMatcher queries will match the new address the same way as the
old, instead of accidentally matching what had been the base register
as the new scaled register, and then failing to match the scaled register.
This fixes some problems with address-mode sinking multiple muls into a
block, which will be a lot more common with some upcoming
LoopStrengthReduction changes.

c7b8814bb4 give MCAsmInfo a 'has little endian' bit. This is unfortunate, but 
I really want clients of the streamer to be able to say "emit this
64-bit integer" and have it get broken down right by the streamer.

I may change this in the future, we'll see how it works out.
