add more showing of my work.

3823432a57 The logic inside getMulExpr to simplify {a,+,b}*{c,+,d} was wrong, which was 
visible given a=b=c=d=1, on iteration #1 (the second iteration). Replace it with
correct math. Fixes PR10383!

9b5a242546 Add a new MC bit for NaCl (Native Client) mode. NaCl requires that certain 
instructions are more aligned than the CPU requires, and adds some additional
directives, to follow in future patches. Patch by David Meyer!

0c1a5d2067 Use canonical forms for the branch probability zero heutistic. 
- Drop support for X >u 0, it's equivalent to X != 0 and should be canonicalized into the latter.
- Add X < 1 -> unlikely, which is what instcombine canonicalizes X <= 0 into.
- Add X > -1 -> likely, which is what instcombine canonicalizes X >= 0 into.

CMake build.

dbea8de893 The insertion point for the loads is right before the llvm.eh.exception 
call. The call may be in the same BB as the landingpad instruction. If that's
the case, then inserting the loads after the landingpad inst, but before the
extractvalues, causes undefined behavior.

05f809efff Fix a truly heinous bug in DAGCombine related to AssertZext. 
If we have a chain of zext -> assert_zext -> zext -> use, the first zext would get simplified away because of the later zext, and then the later zext would get simplified away because of the assert.  The solution is to teach SimplifyDemandedBits that assert_zext demands all of the high bits of its input, rather than only those demanded by its users.  No testcase because the only example I have manifests as llvm-gcc miscompiling LLVM, and I haven't found a smaller case that reproduces this problem.
Fixes <rdar://problem/10063365>.

ef8527b836 Pseudo CMOV instructions don't clobber EFLAGS. 
The explanation about a 0 argument being materialized as xor is no
longer valid.  Rematerialization will check if EFLAGS is live before
clobbering it.

The code produced by X86TargetLowering::EmitLoweredSelect does not
clobber EFLAGS.

This causes one less testb instruction to be generated in the cmov.ll
test case.
