929e4da68b Stop tracking unused registers in VirtRegMap.
The information was only used by the register allocator in
StackSlotColoring.

334575e79b Remove the -color-ss-with-regs option.
It was off by default.

The new register allocators don't have the problems that made it
necessary to reallocate registers during stack slot coloring.

cfa8101409 Switch PBQP to the modern InlineSpiller framework.
It is worth noting that the old spiller would split live ranges around
basic blocks. The new spiller doesn't do that.

PBQP should do its own live range splitting with
SplitEditor::splitSingleBlock() if desired.  See
RAGreedy::tryBlockSplit().

RegAllocGreedy has been the default for six months now.

Deleting RegAllocLinearScan makes it possible to also delete
VirtRegRewriter and clean up the spiller code.

afe153c53f Fixed the MCJIT so that it can emit not only instance
methods but also class methods for Objective-C.

Clang emits Objective-C method names with '\1' at the
beginning, and the JIT has pre-existing logic to try
prepending a '\1' when searching a module for an
instance method (that is, a method whose name begins
with '-').  I simply extended it to do the same thing
when it encountered a class method (a method whose
name begins with '+').

d1ac3a47f2 The dwarf standard says that the only differences between a out-of-line
instance and a concrete inlined instance are the use of DW_TAG_subprogram
instead of DW_TAG_inlined_subroutine and the who owns the tree.

We were also omitting DW_AT_inline from the abstract roots. To fix this,
make sure we mark abstract instance roots with DW_AT_inline even when
we have only out-of-line instances referring to them with DW_AT_abstract_origin.

FileCheck is not a very good tool for tests like this, maybe we should add
a -verify mode to llvm-dwarfdump.

7aef99b677 ARM vldm and vstm VFP instructions can take a data type suffix.
It's ignored by the assembler when present, but is legal syntax. Other
instructions have something similar, but for some mnemonics it's
only sometimes not significant, so this quick check in the parser will
need refactored into something more robust soon-ish. This gets some
basics working in the meantime.
