Simplify the logic of getting hold of a PHI predecessor block.
...
There is now a direct way from value-use-iterator to incoming block in PHINode's API.
This way we avoid the iterator->index->iterator trip, and especially the costly
getOperandNo() invocation. Additionally there is now an assertion that the iterator
really refers to one of the PHI's Uses.

Dynamic allocas cause inefficient codegen and we shouldn't

the tests.

Rewrite all the 'PromoteLocallyUsedAlloca[s]' logic. With the power of
...
LargeBlockInfo, we can now dramatically simplify their implementation
and speed them up at the same time. Now the code has time proportional
to the number of uses of the alloca, not the size of the block.
This also eliminates code that tried to batch up different allocas which
are used in the same blocks, and eliminates the 'retry list' logic which
was baroque and no unneccesary. In addition to being a speedup for crazy
cases, this is also a nice cleanup:

Change create*Pass factory functions to return Pass* instead of

LoopPass*.
- Although less precise, this means they can be used in clients

eventually includes things using dynamic_cast). This was the
simplest solution that presented itself, but I am happy to use a
better one if available.
