The headers in the compiler's own resource include directory are
system headers, which means we don't stat() them eagerly when loading
a module. Use module.map as a proxy for these headers and the compiler
itself. Fixes <rdar://problem/13856838>.

Adding a feature to optionally reformat code changed by the migrator. Like
LibFormat, can choose between built-in styles (LLVM, Mozilla, Google, Chromium)
or use a YAML-format config file.

Instantiate RegisterContextCore... based on getOS() instead of with
compile-time #ifdef-ery.
The assert()s here are unfortunate, but better than crashing with no
explanation. (This would previously happen for an unsupported
architecture, anyhow.)
We should add an equivalent OS and architecture test to
ProcessElfCore::DoLoadCore() and cleanly report the error to the user.

Use the function attributes to pass along the stack protector buffer size.
Now that we have robust function attributes, don't use a command line option to
specify the stack protecto buffer size.

On FreeBSD I see that Arch, Vendor, OS, and Environment are unchanged
after this call (for x86_64, at least), and core debugging works without
it.
If we need to restore it we should be able to switch on
arch.GetTriple.getOS() instead of a compile-time #ifdef.
Thanks to Daniel Malea for testing on Linux.

Enable parsing all 32 floating point control registers $0-31 and stop trying to
parse floating point condition code register $fcc0. Also, return ParseFail if
the operand being parsed is not in the expected format.

There already have two "dead" functions, initialize{IPO|IPA}, defined for
similar purpose. I decide not to call these two functions for two reasons:
o. they don't cover all LTO passes (which will soon be separated into IPO
and post-IPO passes)
o. We have not yet figured out the right passes and the ordering for IPO
and post-IPO stages, meaning this change is only for the time being.
Since LTO passes are registered, we are now able to print IR before and
after particular point.
For OSX users:
--------------
"...-Wl,-mllvm -Wl,-print-after=<pass-name>" will print IR after the
specified pass.
For Other UNIX with GNU gold linker:
------------------------------------
"-Wl,-plugin-opt=-print-after=<pass-name>" should work.
(NOTE: no need for "-Wl,-mllvm")
Strip "-Wl," if flags are fed directly to linker instead of clang/clang++.

Variadic MC instructions don't note whether the variable operands
are uses or defs, so mayAffectControlFlow() must conservatively
assume they are defs and return true if the PC is in the operand
list.

We don't have tests for the effect of if-conversion loops because it requires a big test (that includes if-converted loops) and it is difficult to find and balance a loop to do the right thing.

After the first operation, the buffer contents has changed and thus all
other operations would be invalid. Executing the operations in reversed
order should fix this.

Option aliases in option groups were previously disallowed by an assert.
As far as I can tell, there was no technical reason for this, and I would
like to be able to put cl.exe compatible options in their own group for Clang,
so let's change the assert.

Previously (in tools other than TSan) the entire prefix of the path had to mach
the argument. With this change, only some suffix of the prefix has to match.
This is the same way this flag works in TSan.

Summary:
Add support for overloaded matchers.
This composes with other features, like supporting polymorphic matchers.

instructions. With this patch:
1. ldr.n is recognized as mnemonic for the short encoding
2. ldr.w is recognized as menmonic for the long encoding
3. ldr will map to either short or long encodings depending on the size of the offset

This matches gnu archive behavior and since archive member order can change
which member is used, not changing the order on replacement looks like the
right thing to do.
This patch also refactors the logic for which archive member to keep and
whether to move it to a helper function (computeInsertAction). The
nesting in computeNewArchiveMembers was getting a bit confusing.

Based on Peter Collingbourne's destructor patches.
Prior to this change, clang was considering ?1 to be the complete
destructor and the base destructor, which was wrong. This lead to
crashes when clang tried to emit two LLVM functions with the same name.
In this ABI, TUs with non-inline dtors might not emit a complete
destructor. They are emitted as inline thunks in TUs that need them,
and they always delegate to the base dtors of the complete class and its
virtual bases. This change uses the DeferredDecls machinery to emit
complete dtors as needed.
Currently in clang try body destructors can catch exceptions thrown by
virtual base destructors. In the Microsoft C++ ABI, clang may not have
the destructor definition, in which case clang won't wrap the virtual
virtual base destructor calls in a try-catch. Diagnosing this in user
code is TODO.
Finally, for classes that don't use virtual inheritance, MSVC always
calls the base destructor (?1) directly. This is a useful code size
optimization that avoids emitting lots of extra thunks or aliases.
Implementing it also means our existing tests continue to pass, and is
consistent with MSVC's output.
We can do the same for Itanium by tweaking GetAddrOfCXXDestructor, but
it will require further testing.

GNU ar when not given the a or b modifiers replaces archive members in the
same location of the old ones. I am about to implement that in llvm-ar. For
now, just don't depend on the current llvm-ar behavior on this test.

No functionality change.
In Sema helper functions:
* renamed isTypeName as HasTypenameKeyword
In UsingDecl:
* renamed get/setUsingLocation to get/setUsingLoc
* renamed is/setTypeName as has/setTypename
