14b9c222c6 Add forgotten tests that the cleanup flag is cleared if there 
is a catch-all landingpad clause.

b4c8b2d9fa Inlining often produces landingpad instructions with repeated 
catch or repeated filter clauses.  Teach instcombine a bunch
of tricks for simplifying landingpad clauses.  Currently the
code only recognizes the GNU C++ and Ada personality functions,
but that doesn't stop it doing a bunch of "generic" transforms
which are hopefully fine for any real-world personality function.
If these "generic" transforms turn out not to be generic, they
can always be conditioned on the personality function.  Probably
someone should add the ObjC++ personality function.  I didn't as
I don't know anything about it.

e1d5ae73ac LSR: rewrite inner loops only. 
Rewriting the entire loop nest now requires -enable-lsr-nested.
See PR11035 for some performance data.
A few unit tests specifically test nested LSR, and are now under a flag.

2f96de340f PTX: MC-ize the PTX back-end (patch 1 of N) 
Lay some groundwork for converting to MC-based asm printer. This is the first
of probably many patches to bring the back-end back up-to-date with all of the
recent MC changes.

c4fcff419c Check in a patch that has already been code reviewed by Owen that I'd forgotten to commit. 
Build on previous patches to successfully distinguish between an M-series and A/R-series MSR and MRS instruction. These take different mask names and have a *slightly* different opcode format.

Add decoder and disassembler tests.

Improvement on the previous patch - successfully distinguish between valid v6m and v7m masks (one is a subset of the other). The patch had to be edited slightly to apply to ToT.

This also enables domain swizzling for AVX code which required a few

6aaaadc188 Convert more tests over to the new atomic instructions. 
I did not convert Atomics-32.ll and Atomics-64.ll by hand; the diff is autoupgrade output.

The wmb test is gone because there isn't any way to express wmb with the new atomic instructions; if someone really needs a non-asm way to write a wmb on Alpha, a platform-specific intrisic could be added.
