610bebf777 After physreg coalescing, physical registers might not have live ranges where 
you would expect.

Don't assert on that case, just give up.

This fixes PR7513.

d843b3925f Add more special treatment for inline asm in RegAllocFast. 
When an instruction has tied operands and physreg defines, we must take extra
care that the tied operands conflict with neither physreg defs nor uses.

The special treatment is given to inline asm and instructions with tied operands
/ early clobbers and physreg defines.

This fixes PR7509.

710ac0711f extend ArgOperand interface: setArgOperand 
(in both CallInst and InvokeInst)

also add a (short-lived) constant to CallInst, that names
the operand index of the first call argument. This is
strictly transitional and should not be used for new code.

d50e9e2566 Fix PR7328: when turning a tail recursion into a loop, need to preserve

the return value, but for the moment just fix the miscompile.

ccd9bcca14 Clean up some problems with extra CFG edges being introduced during 
if-conversion.  The RemoveExtraEdges function doesn't work for blocks that
end with unanalyzable branches, so in those cases, the "extra" edges must
be explicitly removed.  The CopyAndPredicateBlock and MergeBlocks methods
can also avoid copying successor edges due to branches that have already
been removed.  The latter case is especially helpful when MergeBlocks is
called for handling "diamond" if-conversions, where otherwise you can end
up with some weird intermediate states in the CFG.  Unfortunately I've
been unable to find cases where this cleanup actually makes a significant
difference in the code.  There is one test where we manage to remove an
empty block at the end of a function.  Radar 6911268.

4f5d84e4ad When creating X86 MUL8 and DIV8 instructions, make sure we don't produce 
CopyFromReg nodes for aliasing registers (AX and AL). This confuses the fast
register allocator.

Instead of CopyFromReg(AL), use ExtractSubReg(CopyFromReg(AX), sub_8bit).

This fixes PR7312.

e39e06af38 Thumb2ITBlockPass: Fix a possible dereference of an invalid iterator. This was

unfortunate.
