clang-format vs plugin: set version number from cmake (PR20307)

Previously it was hard-coded to 1.0, which meant the installer would
not install the plugin over previous versions.

This commit makes us use LLVM's major.minor.patch version from cmake,
or whatever CLANG_FORMAT_VS_VERSION is set to when configuring the build.

It's pretty dirty to update a configuration file in the source directory
from the cmake build like this. However, the plugin build is already
dirty in this regard since it builds in the source dir when visual studio,
and then copies out the resulting vsix.

-fms-extensions: Implement half of #pragma init_seg

Summary:
This pragma is very rare.  We could *hypothetically* lower some uses of
it down to @llvm.global_ctors, but given that GlobalOpt isn't able to
optimize prioritized global ctors today, there's really no point.

If we wanted to do this in the future, I would check if the section used
in the pragma started with ".CRT$XC" and had up to two characters after
it.  Those two characters could form the 16-bit initialization priority
that we support in @llvm.global_ctors.  We would have to teach LLVM to
lower prioritized global ctors on COFF as well.

This should let us compile some silly uses of this pragma in WebKit /
Blink.

Avoid crash if default argument parsed with errors.

If function parameters have default values, and that of the second
parameter is parsed with errors, function declaration would have
a parameter without default value that follows a parameter with
that. Such declaration breaks logic of selecting overloaded
function. As a solution, put opaque object as default value in such case.

This patch fixes PR20055.

Sema: correct handling for __va_start for WoA

Windows ARM indicates __va_start as a variadic function.  However, the function
itself is treated as having 4 formal arguments:
  - (out) pointer to the va_list
  - (in) address of the last named argument
  - (in) slot size for the type of the last argument
  - address of the last named argument

The last argument does not seem to have any bearing on codegen, and thus is not
explicitly type checked at this point.

Unlike the previous handling for __va_start, it does not currently validate if
the parameter is the last named parameter (it seems that MSVC currently accepts
this).
