First, taking advantage of the fact that the virtual base registers are allocated in order of the local frame offsets, remove the quadratic register-searching behavior. Because of the ordering, we only need to check the last virtual base register created.
Second, store the frame index in the FrameRef structure, and get the frame index and the local offset from this structure at the top of the loop iteration. This allows us to de-nest the loops in insertFrameReferenceRegisters (and I think makes the code cleaner). I also moved the needsFrameBaseReg check into the first loop over instructions so that we don't bother pushing FrameRefs for instructions that don't want a virtual base register anyway.
Lastly, and this is the only functionality change, avoid the creation of single-use virtual base registers. These are currently not useful because, in general, they end up replacing what would be one r+r instruction with an add and a r+i instruction. Committing this removes the XFAIL in CodeGen/PowerPC/2007-09-07-LoadStoreIdxForms.ll
Jim has okayed this off-list.

This reverts commit 342d92c7a0adeabc9ab00f3f0d88d739fe7da4c7.
Turns out we're going with a different schema design to represent
DW_TAG_imported_modules so we won't need this extra field.

Adding DIImportedModules to DIScopes.2013-03-27T00:07:26ZDavid Blaikiedblaikie@gmail.com2013-03-27T00:07:26Zurn:sha1:342d92c7a0adeabc9ab00f3f0d88d739fe7da4c7
This is just the basic groundwork for supporting DW_TAG_imported_module but I
wanted to commit this before pushing support further into Clang or LLVM so that
this rather churny change is isolated from the rest of the work. The major
churn here is obviously adding another field (within the common DIScope prefix)
to all DIScopes (files, classes, namespaces, lexical scopes, etc). This should
be the last big churny change needed for DW_TAG_imported_module/using directive
support/PR14606.

Include '.test' suffix in target specific lit configs that need it2013-03-18T20:31:44ZDavid Blaikiedblaikie@gmail.com2013-03-18T20:31:44Zurn:sha1:e68f0b650e32c1993c5d4c92e04cb3d7b7588010
Apparently my final cleanup to use a relevant suffix for these tests before
committing r176831 caused them to stop running since lit wasn't configured to
run tests with that suffix in those directories (why don't we just have a
global suffix list?). So, add the suffix to the relevant directories & fix the
test that has bitrotted over the last week due to my debug info schema changes.

This reverts commit aac7922b8fe7ae733d3fe6697e6789fd730315dc. I am reverting the
commit since it broke the phase 1 public buildbot for a few hours.
