This new register allocator is initially identical to RegAllocBasic, but it will
receive all of the tricks that RegAllocBasic won't get.

RegAllocGreedy will eventually replace linear scan.

because the diagnostic client for one of the AST
contexts is NULL.  Now we provide a form of Miranda
rights to AST contexts: they are provided with a very
simple diagnostic client if they do not have one
themselves.

build: Don't force -flat_namespace or '-undefined suppress' on unsuspecting users of LLVM makefiles, these options really shouldn't be used on Darwin.

as the args and the envs to the launched process.

o lldbtest.py:

  Forgot to check in some assertion messages changes for lldbtest.py.

o dotest.py:

  Also add "api" category to the default lldb log option list.

Launch the process with ['X', 'Y', 'Z'] as the args to make argc == 4 and verify that's the case,
plus some other EvaluateExpression() calls.

Minor optimization to the use of IntervalMap iterators. They are fairly
heavyweight, so prefer SI.valid() over SI != end().

the order of the bytes in the data stream is flipped around.

so they can be used in the implementations of other intrinsics.

        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

This speeds up RegAllocBasic by 20%, not counting releaseMemory which becomes
way faster.

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.
