This patch fixes a problem encountered by the CellSPU backend where variants
...
were being pruned in patterns where a variable was used more than once, e.g.:
(or (and R32C:$rA, R32C:$rC), (and R32C:$rB, (not R32C:$rC)))
In this example, $rC is used more than once and is actually significant to
instruction selection pattern matching when commuted variants are produced.
This patch scans the pattern's clauses and collects the variables, creating
a set of variables that are used more than once. TreePatternNode::isIsomorphicTo()
also understands that multiply-used variables are significant.

Add a target lowering hook to control whether it's worthwhile to compress fp constant.
...
For x86, if sse2 is available, it's not a good idea since cvtss2sd is slower than a movsd load and it prevents load folding. On x87, it's important to shrink fp constant since fldt is very expensive.

Remove the first layer of support for "portability" warnings. This is
...
theoretically useful, but not useful in practice. It adds a bunch of
complexity, and not much value. It's best to nuke it. One big advantage
is that it means the target interfaces will soon lose their SLoc arguments
and target queries can never emit diagnostics anymore (yay). Removing this
also simplifies some of the core preprocessor which should make it slightly
faster.
Ted, I didn't simplify TripleProcessor, which can now have at most one
triple, and can probably just be removed. Please poke at it when you have
time.

Cleaned up typedefs involving StateTy so that we always use "StateTy*" instead of StateTy.
