Core: Make the resolver faster.
In the resolver, we maintain a list of undefined symbols, and when we
visit an archive file, we check that file if undefined symbols can be
resolved using files in the archive. The archive file class provides
find() function to lookup a symbol.
Previously, we call find() for each undefined symbols. Archive files
may be visited multiple times if they are in a --start-group and
--end-group. If we visit a file M times and if we have N undefined
symbols, find() is called M*N times. I found that that is one of the
most significant bottlenecks in LLD when linking a large executable.
find() is not a very cheap operation because it looks up a hash table
for a given string. And a string, or a symbol name, can be pretty long
if you are dealing with C++ symbols.
We can eliminate the bottleneck.
Calling find() with the same symbol multiple times is a waste. If a
result of looking up a symbol is "not found", it stays "not found"
forever because the symbol simply doesn't exist in the archive.
Thus, we should call find() only for newly-added undefined symbols.
This optimization makes O(M*N) O(N).
In this patch, all undefined symbols are added to a vector. For each
archive/shared library file, we maintain a start position P. All
symbols [0, P) are already searched. [P, end of the vector) are not
searched yet. For each file, we scan the vector only once.
This patch changes the order in which undefined symbols are looked for.
Previously, we iterated over the result of _symbolTable.undefines().
Now we iterate over the new vector. This is a benign change but caused
differences in output if remaining undefines exist. This is why some
tests are updated.
The performance improvement of this patch seems sometimes significant.
Previously, linking chrome.dll on my workstation (Xeon 2.4GHz 8 cores)
took about 70 seconds. Now it takes (only?) 30 seconds!

[modules] Rework merging of redeclaration chains on module import.
We used to save out and eagerly load a (potentially huge) table of merged
formerly-canonical declarations when we loaded each module. This was extremely
inefficient in the presence of large amounts of merging, and didn't actually
save any merging lookup work, because we still needed to perform name lookup to
check that our merged declaration lists were complete. This also resulted in a
loss of laziness -- even if we only needed an early declaration of an entity, we
would eagerly pull in all declarations that had been merged into it regardless.
We now store the relevant fragments of the table within the declarations
themselves. In detail:
* The first declaration of each entity within a module stores a list of first
declarations from imported modules that are merged into it.
* Loading that declaration pre-loads those other entities, so that they appear
earlier within the redeclaration chain.
* The name lookup tables list the most recent local lookup result, if there
is one, or all directly-imported lookup results if not.

When we have a symbol, like "NSLog" that we try to call in an expression, make sure we prioritize the external symbols over the internal one.
This is a temporary fix until a more comprehensive fix can be made for finding functions that we call in expressions.
We find "NSLog" in ClangExpressionDeclMap::FindExternalVisibleDecls() in after a call to target->GetImages().FindFunctions(...). Note that there are two symbols: NSLog from CFNetwork which is not external, and NSLog from Foundation which _is_ external. We do something with the external symbol with:
if (extern_symbol)
{
AddOneFunction (context, NULL, extern_symbol, current_id);
context.m_found.function = true;
}
Then later we try to lookup the _Z5NSLogP8NSStringz name and we don't find it so we call ClangExpressionDeclMap::GetFunctionAddress() with "_Z5NSLogP8NSStringz" as the name and the sc_list_size is zero at the "if" statement at line 568 because we don't find the mangled name and we extract the basename "NSLog" and call:
FindCodeSymbolInContext(ConstString(basename), m_parser_vars->m_sym_ctx, sc_list);
sc_list_size = sc_list.GetSize();
and we get a list size of two again, and we proceed to search for the symbol again, this time ignoring the external vs non-external-ness of the symbols that we find. This fix ensures we prioritize the external symbol until we get a real fix from Sean Callanan when he gets back to make sure we don't do multiple lookups for the same symbol we already resolved.

[AVX] Lower / fast-isel scalar FP selects into VBLENDV instructions (PR22483)
This patch reduces code size for all AVX targets and increases speed for some chips.
SSE 4.1 introduced the useless (see code comments) 2-register form of BLENDV and
only in the packed float/double flavors.
AVX subsequently made the instruction useful by adding a 4-register operand form.
So we just need to paper over the lack of scalar forms of this instruction, complicate
the code to choose float or double forms, and use blendv on scalars since all FP is in
xmm registers anyway.
This gives us an approximately 50% speed up for a blendv microbenchmark sequence
on SandyBridge and Haswell:
blendv : 29.73 cycles/iter
logic : 43.15 cycles/iter
No new test cases with this patch because:
1. fast-isel-select-sse.ll tests the positive side for regular X86 lowering and fast-isel
2. sse-minmax.ll and fp-select-cmp-and.ll confirm that we're not firing for scalar selects without AVX
3. fp-select-cmp-and.ll and logical-load-fold.ll confirm that we're not firing for scalar selects with constants.

- we have instructions like vld {dN, dM}, which can't be generated

Fix bitselect for float/double types v2
We need to reinterpret float/double types as uint/ulong in order to
perform the bitwise operations.
This has been tested with piglit, OpenCV, and the ocl conformance tests.
v2:
- Use vector operations rather than splitting vectors into scalar
components.

tsan: fix signal handling during stop-the-world
Long story short: stop-the-world briefly resets SIGSEGV handler to SIG_DFL.
This breaks programs that handle and continue after SIGSEGV (namely JVM).
See the test and comments for details.
This is reincarnation of reverted r229678 (http://reviews.llvm.org/D7722).
Changed:
- execute TracerThreadDieCallback only on tracer thread
- reset global data in TracerThreadSignalHandler/TracerThreadDieCallback
- handle EINTR from waitpid
Add 3 new test:
- SIGSEGV during leak checking
- StopTheWorld operation during signal storm from an external process
- StopTheWorld operation when the program generates and handles SIGSEGVs

Teach lowering to correctly handle invoke statepoint and gc results tied to them. Note that we still can not lower gc.relocates for invoke statepoints.
Also it extracts getCopyFromRegs helper function in SelectionDAGBuilder as we need to be able to customize type of the register exported from basic block during lowering of the gc.result.
