Change pre-regalloc tail duplication to only duplicate indirect branch blocks.
...
The pre-regalloc pass caused some regressions in both compile time and
performance of the generated code, and it did not improve performance, except
for indirect branches. I also moved the check for single-block loops to speed
up the common case when running the taildup pass before reg allocation.

Improve llvm.dbg.declare intrinsic by referring directly to the storage in its first argument, via function-local metadata (instead of via a bitcast).

This patch also cleans up code that expects there to be a bitcast in the first argument and testcases that call llvm.dbg.declare.

Split the TargetAsmParser "ParseInstruction" interface in half:
...
the new ParseInstruction method just parses and returns a list of
target operands. A new MatchInstruction interface is used to
turn the operand list into an MCInst.
This requires new/deleting all the operands, but it also gives
targets the ability to use polymorphic operands if they want to.

Don't fold insufficiently aligned ldr/str into ldm/stm instructions.
...
An unaligned ldr causes a trap, and is then emulated by the kernel with
awesome performance. The darwin kernel does not emulate unaligned ldm/stm
Thumb2 instructions, so don't generate them.
This fixes the miscompilation of Multisource/Applications/JM/lencod for Thumb2.
Generating unaligned ldr/str pairs from a 16-bit aligned memcpy is probably
also a bad idea, but that is beyond the scope of this patch.

When the visitSub method was split into visitSub and visitFSub, this xform was
...
added to the FSub version. However, the original version of this xform guarded
against doing this for floating point (!Op0->getType()->isFPOrFPVector()).
This is causing LLVM to perform incorrect xforms for code like:
void func(double *rhi, double *rlo, double xh, double xl, double yh, double yl){
double mh, ml;
double c = 134217729.0;
double up, u1, u2, vp, v1, v2;
up = xh*c;
u1 = (xh - up) + up;
u2 = xh - u1;
vp = yh*c;
v1 = (yh - vp) + vp;
v2 = yh - v1;
mh = xh*yh;
ml = (((u1*v1 - mh) + (u1*v2)) + (u2*v1)) + (u2*v2);
ml += xh*yl + xl*yh;
*rhi = mh + ml;
*rlo = (mh - (*rhi)) + ml;
}
The last line was optimized away, but rl is intended to be the difference
between the infinitely precise result of mh + ml and after it has been rounded
to double precision.
