bb5174246b Fix edge cases of ARM shift operands in arith instructions.
As before with load instructions, oddities like "asr #32", "rrx" could
be printed incorrectly.

Patch by Chris Lidbury.

93c7c449a1 Fix the handling of edge cases in ARM shifted operands.
This patch fixes load/store instructions to handle less common cases
like "asr #32", "rrx" properly throughout the MC layer.

f5091b476c Casting: assert that pointer arguments to isa<> are non-null.
This silences several analyzer warnings within LLVM, and provides a slightly
nicer crash experience when someone calls isa<>, cast<>, or dyn_cast<> with
a null pointer.

d54a6b56a9 Fix a case where the new SROA pass failed to zap dead operands to
selects with a constant condition. This resulted in the operands
remaining live through the SROA rewriter. Most of the time, this just
caused some dead allocas to persist and get zapped by later passes, but
in one case found by Joerg, it caused a crash when we tried to *promote*
the alloca despite it having this dead use. We already have the
mechanisms in place to handle this, just wire select up to them.

7b451cf356 Have the DbgVariable "isArtificial" and "isObjectPointer" not

that captured block and lambda vars that don't happen to
be arguments could be an argument pointer.
