pthread_cancel is broken on Mac OS X (it only works if the thread
you want to kill calls pthread_testcancel, which is never the situation
when you need async cancelation).
Anyway async cancelation is risky, it may leave bc_ctx in an inconsistent state.
So rather than doing using pthread_cancel (or pthread_kill+siglongjmp)
just insert the timeout checks into the JITed code directly.
These are inserted in each loop, if the loop's tripcount is unknown, or
higher than a threshold. They are also inserted after a certain amount
of APIcalls are made (even in absence of loops).
Note that 'loop' in this sense is not LLVM's notion of a natural loop,
it is simply a BB which is reachable both directly and via a backedge.
For example this doesn't contain natural loops but contains backedges (and a
potential infinite loop):
int foo(int a)
{
int x=4;
if (a == 42)
goto head2;
head:
x++;
head2:
if (a >= 2) {
x += 3;
goto head;
} else if (a >= 0) {
x += 9;
goto head;
}
return x;
}

Add findNearestCommonDominator() for PostDominators.
Add a missing interface to be able to call findNearestCommonDominator
for a PostDominanceTree. The function itself is already implemented in
DominatorTreeBase. The interface however was only added to the
DominatorTree class, but not the PostDominatorClass.

teach tblgen to be more aggressive when factoring CheckType nodes.
Now it will factor things like this:
CheckType i32
...
CheckOpcode ISD::AND
CheckType i64
...
into:
SwitchType:
i32: ...
i64:
CheckOpcode ISD::AND
...
This shrinks hte table by a few bytes, nothing spectacular.
