a switch or goto somewhere in the function.  Indirect gotos trigger the
jump-checker regardless, because the conditions there are slightly more
elaborate and it's too marginal a case to be worth optimizing.

Turns off the jump-checker in a lot of cases in C++.  rdar://problem/7702918

the magic of inline assembly.  Essentially we use read and write hazards
on the set of local variables to force flushing locals to memory
immediately before any protected calls and to inhibit optimizing locals
across the setjmp->catch edge.  Fixes rdar://problem/8160285

call Objective-C methods from expressions.  Also added
some more logging to the function-calling thread plan
so that we can see the registers when a function
finishes.

Also documented things maybe a bit better.

exactly what bugpoint expected it to do.

There was also only one user of
BlockExtractorPass(const std::vector<BasicBlock*> &B), so just remove it and
make BlockExtractorPass read BlockFile.

This fixes bugpoint's block extraction.

Nick, please review.

Add an initial implementation of PHI translation for LazyValueInfo.  This involves rolling back some

formerly rejected by the FE, so asserted in the BE; now the FE only
warns, so we treat it as a legitimate fatal error in PPC BE.
This means the test for the feature won't pass, so it's xfail'd.
