0a98bc5619 tblgen/AsmMatcher: Always emit the match function as 'MatchInstructionImpl', 
target specific parsers can adapt the TargetAsmParser to this.

cb6029f089 configure: Add detection of the linker version string. 
- Review appreciated, as long as you understand that I understand that this is
   a horrible hack.

90e835b327 Clean up ConstantRange a bit: 
- remove ashr which never worked.
 - fix lshr and shl and add tests.
 - remove dead function "intersect1Wrapped".
 - add a new sub method to subtract ranges, with test.

54027cf446 Don't use unsigned char for alignments in TargetData. There aren't 
that many of these things, so the memory savings isn't significant,
and there are now situations where there can be alignments greater
than 128.

245a1faf76 Implement register class inflation. 
When splitting a live range, the new registers have fewer uses and the
permissible register class may be less constrained. Recompute the register class
constraint from the uses of new registers created for a split. This may let them
be allocated from a larger set, possibly avoiding a spill.

1ab2fab3af 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.

8a7a43a1cb 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.

8303a64b0a 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.

and removing it catches the mistake of passing a ValueMap by
copy rather than by reference.

39c49e3e17 Use the "isCompare" machine instruction attribute instead of calling the 
relatively expensive comparison analyzer on each instruction. Also rename the
comparison analyzer method to something more in line with what it actually does.

This pass is will eventually be folded into the Machine CSE pass.
