37bf33ccff Add an Intraprocedural form of BasicAliasAnalysis, which aims to 
properly handles instructions and arguments defined in different
functions, or across recursive function iterations.

2a4e6d0e34 Fix Thumb encoding of VMOV (scalar to ARM core register). The encoding is 
the same as ARM except that the condition code field is always set to ARMCC::AL.

5ae34cf120 Unlike other targets, ARM now uses BUILD_VECTORs post-legalization so they 
can't be changed arbitrarily by the DAGCombiner without checking if it is
running after legalization.

94738aa18e In asm's, output operands with matching input constraints 
have to be registers, per gcc documentation.  This affects
the logic for determining what "g" should lower to.  PR 7393.
A couple of existing testcases are affected.

61e6433440 After physreg coalescing, physical registers might not have live ranges where 
you would expect.

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

2ec7bf335a 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.

47e6a5f906 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.

d3a1ef7fea minor cleanup to SROA: when lowering type unsafe accesses to 
large integers, the first inserted value would always create
an 'or X, 0'.  Even though this is trivially zapped by
instcombine, don't bother creating this pointless instruction.
