b9a6da20e8 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.

aee71b4e81 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.

"icmp lhs, rhs" into "cmp rhs, lhs". This should fix PR5979.

882cb240a6 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.

d3d283dc19 Dwarf EH prepare needs to be run after SjLj prepare. Otherwise, 
catch info can get misplaced when a selector ends up more than one block
removed from the parent invoke(s). This could happen when a landing pad is
shared by multiple invokes and is also a target of a normal edge from
elsewhere.

97a8d154fb ARM "l" constraint for inline asm means R0-R7, also for Thumb2. 
This is consistent with llvm-gcc's arm/constraints.md.

Certain instructions (e.g. CBZ, CBNZ) require a low register, even in Thumb2
mode.

5fdcc970a2 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.
