Summary:
Handle -extra-arg and -extra-arg-before options in the
CommonOptionsProvider so they can be used in all clang tools. Adjust arguments
in a CompilationDatabase wrapper instead of adding ArgumentsAdjuster to the
tool.

mingw64's headers implement fabs by calling __builtin_fabs, so using the
library call results in an infinite loop. If the backend legalizes
@llvm.fabs as a call to fabs later, things should work out, as the crt
provides a definition.

Now we don't warn on this code:
void __stdcall f(void);
void __stdcall f();
My previous commit regressed this functionality because I didn't update
the relevant test case which used a definition.

We already have a warning on the call sites of code like this:
void f() { }
void g() { f(1, 2, 3); }
t.c:2:21: warning: too many arguments in call to 'f'
We can limit ourselves to diagnosing unprototyped forward declarations
of f to cut down on noise.

parameters with nonnull attribute when comparison is always
true/false. Patch causes false positive when parameter is
modified in the function.

Local variables are not initialized, and every target has
been (incorrectly) ignoring the unnecessary request for
zero initialization.

Trying to import or export such classes doesn't make sense, and Clang
would assert trying to export vtables for them.
This is consistent with how we treat functions with internal linkage,
but it is stricter than MSVC so we may have to back down if it breaks
real code.

This reverts commit b5bdb2ef59ab922bcb4d6e843fffaee1f7f68a8c.
This doesn't really seem necessary on second though and causes problems
with C++ enum formatting.

It turns out that MinGW never dllimports of exports inline functions.
This means that code compiled with Clang would fail to link with
MinGW-compiled libraries since we might try to import functions that
are not imported.
To fix this, make Clang never dllimport inline functions when targeting
MinGW.

If g:clang_format_path is set in the vimrc, that path will take precedence over
the hard coded path (which is reliant on the PATH environment variable). This
provides an easy mechanism for switching the selected clang-format binary during
development.

It says there is a narrowing conversion when we assign it to an unsigned
3 bit bitfield.
Also, use unsigned instead of size_t for the Size field of the struct in
question. Otherwise they won't run together in MSVC or clang-cl.

The most complex aspect of the convention is the handling of homogeneous
vector and floating point aggregates. Reuse the homogeneous aggregate
classification code that we use on PPC64 and ARM for this.
This convention also has a C mangling, and we apparently implement that
in both Clang and LLVM.

Summary:
The Itanium ABI approach of using offset-to-top isn't possible with the
MS ABI, it doesn't have that kind of information lying around.
Instead, we do the following:
- Call the virtual deleting destructor with the "don't delete the object
flag" set. The virtual deleting destructor will return a pointer to
'this' adjusted to the most derived class.
- Call the global delete using the adjusted 'this' pointer.
