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. BURR scheduler should also check if inline asm nodes can clobber "live" physical registers. Previously it was only checking target nodes with implicit defs.

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.

implement support for propagating *features* down to the code generator
...
and defining target-specific macros based on them (like __SSE3__ and

driver support, which will translate things like -msse3 into a -mattr
feature. Until this work is done, the code in clang.cpp is disabled and
the X86TargetInfo ctor still defaults to SSE2. With these two things
changed, this code will work. PR3634
