as in the testcase in PR5259.

JITEmitter.

I'm gradually making Functions auto-remove themselves from the JIT when they're
destroyed. In this case, the Function needs to be removed from the JITEmitter,
but the map recording which Functions need to be removed lived behind the
JITMemoryManager interface, which made things difficult.

This patch replaces the deallocateMemForFunction(Function*) method with a pair
of methods deallocateFunctionBody(void *) and deallocateExceptionTable(void *)
corresponding to the two startFoo/endFoo pairs.

encounters an OEQ or UNE comparison, and update its callers to check
for this return status and recover. This fixes a problem resulting from
the LowerOperation hooks being called from LegalizeVectorOps, because
LegalizeVectorOps only lowers vectors, so OEQ and UNE comparisons may
still be at large. This fixes PR5092.

When an incoming value for a PHI is updated, we must also updated all other
incoming values for the same BB to match, otherwise we create invalid PHIs.

when the invoke had multiple return values: it set the lattice value only on the
extractvalue.
This caused the invoke's lattice value to remain the default (undefined), and
later propagated to extractvalue's operand, which incorrectly introduces
undefined behavior.

- Extend clang_createIndex() to support PCH and diagnostic 'filtering'. This seems cleaner to me without sacrificing much flexibility.

- Remove clang_wantOnlyLocalDeclarations().

- Remove 'displayDiagnostics' arguments to clang_createTranslationUnitFromSourceFile() and clang_createTranslationUnit().

- Have clang_createTranslationUnitFromSourceFile() strip the '-o <outfile>' command line arguments if they exist. Document this semantic in the header. Also verify we have a valid ASTUnit before telling it to 'unlinkTemporaryFile()'.
