d4eea7c10d Let target asm backends see assembler flags as they go by. Use that to handle 
thumb vs. arm mode differences in WriteNopData().

77e7ad803a Move RABasic::addMBBLiveIns to the base class, it is generally useful. 
Minor optimization to the use of IntervalMap iterators. They are fairly
heavyweight, so prefer SI.valid() over SI != end().

ba5edcfe05 VLDR fixups need special handling under Thumb. While the encoding is the same, 
the order of the bytes in the data stream is flipped around.

790fe1d064 Layout each section independently. With the testcase in PR8711: 
before:
        4 assembler - Number of assembler layout and relaxation steps
    78563 assembler - Number of emitted assembler fragments
  8693904 assembler - Number of emitted object file bytes
   271223 assembler - Number of evaluated fixups
330771677 assembler - Number of fragment layouts
     5958 assembler - Number of relaxed instructions
  2508361 mcexpr    - Number of MCExpr evaluations

real	0m26.123s
user	0m25.694s
sys	0m0.388s

after:

      4 assembler - Number of assembler layout and relaxation steps
  78563 assembler - Number of emitted assembler fragments
8693904 assembler - Number of emitted object file bytes
 271223 assembler - Number of evaluated fixups
 231507 assembler - Number of fragment layouts
   5958 assembler - Number of relaxed instructions
2508361 mcexpr    - Number of MCExpr evaluations

real	0m2.500s
user	0m2.113s
sys	0m0.273s

And yes, the outputs are identical :-)

9d6472e894 Switch LiveIntervalUnion from std::set to IntervalMap. 
This speeds up RegAllocBasic by 20%, not counting releaseMemory which becomes
way faster.

3bd9b95b4d Fix a bad prologue / epilogue codegen bug where the compiler would emit illegal 
vpush instructions to save / restore VFP / NEON registers like this:
vpush {d8,d10,d11}
vpop {d8,d10,d11}

vpush and vpop do not allow gaps in the register list.

before.

54a78a9787 Remove the code from Function::dropAllReferences which replaced 
uses of the function's blocks with undef. This code isn't needed,
because BasicBlock's destructor handles such uses. Also, undef isn't
correct, since blockaddresses may still be used for comparisons
with null.

an assert, at least.
