- Implement asm parsing support for LDRT, LDRBT, STRT, STRBT and
  {STR,LDC}{2}_{PRE,POST} fixing the encoding wherever is possible.
- Move all instructions which use am2offset without a pattern to use
  addrmode2.
- Add a new encoding bit to describe the index mode used and teach
  printAddrMode2Operand to check by the addressing mode which index
  mode to print.
- Testcases

We don't expect the real "powf()" on some hosts (and powf() would be available on other hosts).
For consistency, std::pow(double,double) may be called instead.
Or, precision issue might attack us, to see unstable regalloc and stack coloring.

InstCombine: Shrink "fcmp (fpext x), C" to "fcmp x, C" if C can be losslessly converted to the type of x.

__block object copy/dispose helpers for C++ objects with those for
different variables with completely different semantics simply because
they happen to both be no more aligned than a pointer.

Found by inspection.

Also, internalize most of the helper generation logic within CGBlocks.cpp,
and refactor it to fit my peculiar aesthetic sense.

Add code to emulate VSTR ARM instruction (store a floating point register).

Add code to emulate the VLDR Arm instruction (load a floating poitn register).

Static analyzer: fix bug in handling of dynamic_cast<>.  The sink node wouldn't always be the final node, thus causing the state to continue propagating.  Instead,
recover some path-sensitivity by conjuring a symbol.

llvm-svn: 128612

Teach static analyzer about the basics of handling new[].  We still don't simulate constructors, but at least the analyzer doesn't think the return value is uninitialized.

The rematerialized instruction may require a more constrained register class
than the register being spilled. In the test case, the spilled register has been
inflated to the DPR register class, but we are rematerializing a load of the
ssub_0 sub-register which only exists for DPR_VFP2 registers.

The register class is reinflated after spilling, so the conservative choice is
only temporary.

Add "Bits64" utility function.

Convert ValueObject to explicitly maintain the Execution Context in which they were created, and then use that when they update themselves.  That means all the ValueObject evaluate me type functions that used to require a Frame object now do not.  I didn't remove the SBValue API's that take this now useless frame, but I added ones that don't require the frame, and marked the SBFrame taking ones as deprecated.
