DW_AT_APPLE_optimized flag is set when a compile_unit is optimized. The debugger takes advantage of this information some way.

DW_AT_APPLE_flags encodes command line options when certain env. variable is set. This is used by build engineers to track various gcc command lines used by by  a project, irrespective of whether the project used makefile, Xcode or something else.

llvm-gcc patch is next.

Added clang option '--analyzer-display-progress' to indicate that the analyzer should output 'ANALYZE:' messages to display its progress on a source file.

Added virtual method DiagnosticClient::IncludeInDiagnosticCounts().  This is used by Diagnostics to determine if a diagnostic sent to a given DiagnosticClient should be included in the count of diagnostics.  The default implementation of this method returns 'true'.

Implemented DiagCollector::IncludeInDiagnosticCounts() to return 'false' so that the batching of diagnostics for use with BugReporter doesn't mess up the count of real diagnostics.

 - However, these last ones do not actually work; the issue is that
   they translate to batches of options and need to be reparsed. For
   now we just give an unsupported error on them.

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.

testcase from PR3376, and in fact is sufficient to completely
avoid the problem in that testcase.

There's an underlying problem though; TLI.isOperationLegal
considers Custom to be Legal, which might be ok in some
cases, but that's what DAGCombiner is using in many places
to test if something is legal when LegalOperations is true.
When DAGCombiner is running after legalize, this isn't
sufficient. I'll address this in a separate commit.

Refactor how the preprocessor changes a token from being an tok::identifier to a 
keyword (e.g. tok::kw_for).  Instead of doing this in HandleIdentifier, hoist this
common case out into the caller, so that every keyword doesn't have to go through
HandleIdentifier.  This drops time in HandleIdentifier from 1.25ms to .62ms, and
speeds up clang -Eonly with PTH by about 1%.

when we try to inject these parameters into the scope of the function
body before the function itself has been added to the surrounding
scope. Fixes <rdar://problem/6097326>.

This avoids using a dangling pointer.

Reset NumSortedEntries after restoring Cache to avoid extraneous sorts.

This also helps performance.  Pre-alloc-splitting now seems to be an overall win on SPEC.
