Change Parser::ParseCaseStatement to use an iterative approach to parsing
...
multiple sequential case statements instead of doing it with recursion. This
fixes a problem where we run out of stack space parsing 100K directly nested
cases.
There are a couple other problems that prevent this from being useful in
practice (right now the example only parses correctly with -disable-free and
doesn't work with -emit-llvm), but this is a start.
I'm not including a testcase because it is large and uninteresting for
regtesting.
Sebastian, I would appreciate it if you could scrutinize the smart pointer
gymnastics I do.

Fix PR3701. 1. X86 target renamed eflags register to flags. This matches what llvm-gcc generates so codegen knows flags register is being clobbered by inline asm. 2.

The DAG combiner was performing a BT combine. The BT combine had a value of -1,
...
so it changed it into a 31 via the TLO.ShrinkDemandedConstant() call. Then it
would go through the DAG combiner again. This time it had a value of 31, which
was turned into a -1 by TLI.SimplifyDemandedBits(). This would ping pong
forever.
Teach the TLO.ShrinkDemandedConstant() call not to lower a value if the demanded
value is an XOR of all ones.
