Early CFG simplification can fold conditionals down to selects, which is often a good thing, but it can also
...
hide jump threading opportunities by turning control flow into data flow. Run an early JumpThreading pass
(adds approximately an additional 1% to optimization time on SPEC), allowing it to get a shot at these cases
first. Fixes <rdar://problem/8447345>.

Remove LLVM_GLOBAL_VISIBILITY, which is unused, and was not working properly.
...
The problem was that the test for whether a compiler supports it or not was
inaccurate, but has to be accurate: LLVM_LOCAL_VISIBILITY is an optimization
and not needed for correctness, so wrongly thinking a compiler doesn't support
it is not a big deal, but LLVM_GLOBAL_VISIBILITY is for correctness, and not
an optimization: getting it wrong is fatal: it needs to be set based on a
configure test not testing the gcc version. Since dragonegg has moved to a
different scheme, and it was the only user of LLVM_GLOBAL_VISIBILITY, just
remove this macro.

Stop explicitly scheduling domfrontier before the loop passes,

domfrontier (an N^2 analysis) 3 times at clang -O3: once for

the EHPrepare class uses it.
EHPrepare needs to stop using it, this is silly and wasteful.
