df30cf9e61 Transpose the calculation of spill weights such that we are calculating one
register at a time. This turns out to be slightly faster than iterating over
instructions, but more importantly, it allows us to compute spill weights for
new registers created after the spill weight pass has run.

Also compute the allocation hint at the same time as the spill weight. This
allows us to use the spill weight as a cost metric for copies, and choose the
most profitable hint if there is more than one possibility.

The new hints provide a very small (< 0.1%) but universal code size improvement.

6cdb1abe4e Merge the OptimizeExts and OptimizeCmps passes into one PeepholeOptimizer
pass. This pass should expand with all of the small, fine-grained optimization
passes to reduce compile time and increase happiment.

b07ce60981 Next bit of support for the dwarf .file directive. This patch takes the
previously collected info from the .file directives and outputs the encoded
bytes for it.  For now this is only in the Mach-O streamer but at some point
will move to a more generic place.

b000d683c8 ARMBaseRegisterInfo::hasFP() has been broken for a while now. :-(
This will always be false before PEI:
(DisableFramePointerElim(MF) && MFI->adjustsStack())
Which means it's going to make r11 available as a general purpose register even
if -disable-fp-elim is specified. It's working on Darwin only because r7 is
always reserved. But it's obviously broken for other targets.
