Fix some problems with the hidden copy constructors for
ImmutableMap/ImmutableSet found by Clang++.

  - skip .svn directories
  - add a set of excluded filenames so we can easily skip tests

llvm-svn: 86185

Added support for renumbering existing index list elements. Removed some junk from the initial numbering code in runOnMachineFunction.

guarantee.

unsplittable critical edges, which means the introduction of
loops which cannot be transformed to LoopSimplify form. Fix
LoopSimplify to avoid transforming such loops into invalid
code.

LoopSimplify form may not be available.

Fix bug in aggressive antidep breaking; liveness was not updated correctly for regions that do not have antidep candidates.

makes several optimization passes abort in cases where they're currently
silently miscompiling code.

Remove the indirectbr assertion from SplitEdge. Indirectbr is only
a problem for critical edges, and SplitEdge defers to SplitCriticalEdge
to handle those, and SplitCriticalEdge has its own assertion for
indirectbr.

Break anti-dependencies using free registers in a round-robin manner to avoid introducing new anti-dependencies.

This fixes PR5393.

This assert was very conservative to begin with (the error condition is well
covered by tests elsewhere in the code) so we won't miss much by removing it.
