702c4ef9d8 MC/AsmParser: Support .single and .double for embedding floating point literals. 
- I believe more modern 'gas' supports a more enhanced set of arithmetic on
   them, but for now the only thing we can do is emit them as data.

4fc55c0e02 Revert r114703 and r114702, removing the isConditionalMove flag from instructions. After further 
reflection, this isn't going to achieve the purpose I intended it for.  Back to the drawing board!

bcafcce601 Clean up the 'trap' instruction printing a bit. Non-Darwin assemblers don't 
(yet) recognize the 'trap' mnemonic, so we use .short/.long to emit the
opcode directly. On Darwin, however, we do want the mnemonic for more
readable assembly code and better disassembly.

Adjust the .td file to use the 'trap' mnemonic and handle using the binutils
workaround in the assembly printer. Also tweak the formatting of the opcode
values to make them consistent between the MC printer and the old printer.

ce04ba0f70 Represent relocations against local symbols as relocations against the section 
they are in. Both ways should be equivalent, but gas produces relocations
against the section.

0fdee121f7 Fix llvm-extract so that it changes the linkage of all GlobalValues to 
"external" even when doing lazy bitcode loading.  This was broken because
a function that is not materialized fails the !isDeclaration() test.

but the first one. Those will never be executed. There was logic to do this
but it was faulty.

3866797d9a SDISel should not optimize a unconditional branch following a conditional branch 
when the unconditional branch destination is the fallthrough block. The
canonicalization makes it easier to allow optimizations on DAGs to invert
conditional branches. The branch folding pass (and AnalyzeBranch) will clean up
the unnecessary unconditional branches later.

This is one of the patches leading up to disabling codegen prepare critical edge
splitting.

f670bff621 Moved the PBQP allocator class out of the header and back in to the cpp file to hide the gory details. 
Allocator instances can now be created by calling createPBQPRegisterAllocator.

Tidied up use of CoalescerPair as per Jakob's suggestions.

Made the new PBQPBuilder based construction process the default. The internal construction process
remains in-place and available via -pbqp-builder=false for now. It will be removed shortly if the new
process doesn't cause any regressions.

d8735f1db1 Add support for ELF PLT references for ARM MC asm printing. Adding a 
new VariantKind to the MCSymbolExpr seems like overkill, but I'm not sure
there's a more straightforward way to get the printing difference captured.
(i.e., x86 uses @PLT, ARM uses (PLT)).
