Fixed bug in tablegen conversion when source pseudo instruction has
a different number of arguments than the destination instruction.

[ASan] When re-executing the process on OS X, make sure we update the existing DYLD_INSERT_LIBRARIES correctly.
Previously ASan used to hang in an exec loop, because it failed to overwrite the env var value
(see https://code.google.com/p/address-sanitizer/issues/detail?id=159).

This happens when there is both stack realignment and a dynamic alloca in the
function. If we overwrite %esi (rep;movsl uses fixed registers) we'll lose the
base pointer and the next register spill will write into oblivion.

Fixes PR15249 and unbreaks firefox on i386/freebsd. Mozilla uses dynamic allocas
and freebsd a 4 byte stack alignment.

Fix some comments.

- clear ownership: the SpecificBumpPtrAllocator owns all StateNodes
- this allows us to simplify the memoization data structure into a
  std::set (FIXME: figure out whether we want to use a hash based
  data structure).
- introduces StateNode as recursive data structure, instead of using
  Edge and the Seen-map combined to drill through the graph
- using a count to stabilize the penalty instead of relying on the
  container
- pulled out a method to forward-apply states in the end

This leads to a ~40% runtime decrease on Nico's benchmark.

Main FiXME is that the parameter lists of some function get too long.
I'd vote for either pulling the Queue etc into the Formatter proper,
or creating an inner class just for the search algorithm.

Prevent insertion of "vzeroupper" before call that preserves YMM registers, since a caller uses preserved registers across the call.

No functionality change. Also add another cast test.

llvm-svn: 175029

Not all casts are correctly detected yet, but it helps in some cases.
