Bill Wendling d01aee587f Update test to remove the 'unwind' instruction.

Bill Wendling d3c9d971e6 If we are extracting a basic block that ends in an invoke call, we must also 
extract the landing pad block. Otherwise, there will be a situation where the
invoke's unwind edge lands on a non-landing pad.

We also forbid the user from extracting the landing pad block by itself. Again,
this is not a valid transformation.

Bill Wendling 58e58fead1 The eh.selector intrinsic isn't used anymore. Replace the check here with a 
check for the landingpad instruction instead. This check looks at each of the
clauses in the landingpad instruction. If it's a catch clause, it compares the
name directly with the global. If it's a filter clause, it has to look through
each value in the filer to see if any have the prefix.

Argyrios Kyrtzidis 5733271925 In libclang, when visiting preprocessed entities in a source range, use 
PreprocessingRecord's getPreprocessedEntitiesInRange.

Also remove all the stuff that were added in ASTUnit that are unnecessary now
that we do a binary search for preprocessed entities and deserialize only
what is necessary.

Argyrios Kyrtzidis 7f44836998 Introduce local_begin()/local_end() methods in PreprocessingRecord which

Argyrios Kyrtzidis 7c06d8666b [libclang] When getting a source location from a file:line:col triplet 
check whether the requested location points inside the precompiled preamble,
in which case the returned source location will be a "loaded" one.

Argyrios Kyrtzidis 64f6381097 Introduce PreprocessingRecord::getPreprocessedEntitiesInRange() 
which will do a binary search and return a pair of iterators
for preprocessed entities in the given source range.

Source ranges of preprocessed entities are stored twice currently in
the PCH/Module file but this will be fixed in a subsequent commit.

Argyrios Kyrtzidis b4199b659b For SourceManager::isBeforeInTranslationUnit, a location pointing 
inside a macro argument should be regarded as coming before
the location of the expanded tokens.

Argyrios Kyrtzidis b527a7cbf8 [PCH] Preload the PreloadSLocEntries through the SourceManager and 
don't call ReadSLocEntryRecord() directly because the entry may have
already been loaded in which case calling ReadSLocEntryRecord()
directly would trigger an assertion in SourceManager.

Argyrios Kyrtzidis 8b7c08b897 For SourceManager::isBeforeInTranslationUnit, when one location 
points at the inclusion/expansion point of the other, regard this
as coming before the other.

Bill Wendling f0724e8e06 Throw the switch to convert clang to the new exception handling model! 
This model uses the 'landingpad' instruction, which is pinned to the top of the
landing pad. (A landing pad is defined as the destination of the unwind branch
of an invoke instruction.) All of the information needed to generate the correct
exception handling metadata during code generation is encoded into the
landingpad instruction.

The new 'resume' instruction takes the place of the llvm.eh.resume intrinsic
call. It's lowered in much the same way as the intrinsic is.

Akira Hatanaka 79738336a8 Make changes to avoid creating nested CALLSEQ_START/END constructs, which aren't 
yet legal according to comments in LegalizeDAG.cpp:227. 

Memcpy nodes created for copying byval arguments are inserted before
CALLSEQ_START.

The two failing tests reported in PR10876 pass after applying this patch.
