installations. This first selects a set of prefixes and a set of
compatible triples for the current architecture. Once selected, we drive
the search with a single piece of code.

This code isn't particularly efficient as it stands, but its only
executed once. I'm hoping as I clean up the users of this information,
it will also slowly become both cleaner and more efficient.

This also changes the behavior slightly. Previously, we had an ad-hoc
list of prefixes and triples, and we only looked for some triples
beneath specific prefixes and vice versa. This has led to lots of
one-off patches to support triple X, or support lib dir Y. Even without
going to a fully universal driver, we can do better here. This patch
makes us always look first in either 'lib32' or 'lib64' on 32- or 64-bit
hosts (resp.). However, we *always* look in 'lib'.

Currently I have one lingering problem with this strategy. We might find
a newer or better GCC version under a different (but equally compatible)
triple. Fundamentally, this loop needs to be fused with the one below.
That's my next patch.

[analyzer] In UndefBranchChecker, use a node generator which does not create an edge/branching. (ExprEngine should be in charge of generating edges. The checkers should examine the condition and generate PostCondition node if needed.)

This code will replace the version in ARMAsmPrinter.cpp. It creates a new
machine basic block, which is the dispatch for the return from a longjmp
call. It then shoves the address of that machine basic block into the correct
place in the function context so that the EH runtime will jump to it directly
instead of having to go through a compare-and-jump-to-the-dispatch bit. This
should be more efficient in the common case.
