When this header now is a fully regular header within the src tree,
give it a more regular name.

  [compiler-rt] [test] Pass the mingw specific option for increasing stack size

This passes the same option that was added for MSVC builds in
fb5a24b4f03a7 in the corresponding mingw form too.

This fixes the BVGraph tests in the sanitizer unit tests.

  -----------
  [compiler-rt] [ubsan] Fix printing of floats in mingw mode

In mingw mode on x86, long doubles are 80 bit - while MSVC mode uses
long doubles that are equal to regular doubles (on all architectures).

In the case of this formatting function, we're calling a MS CRT
provided printf function which interprets long doubles as 64 bit.

Since the long doubles are equal to regular doubles on all MSVC
platforms, just use regular double formatting. For MSVC environments
there's no difference, but for mingw environments, this avoids the
ambiguity.

This test uses lots of lld-link specific linker options that don't
work as such in mingw command lines.

Mingw toolchains always end up referencing the malloc symbol due to
the CRT startup files.

  Log Message:
  -----------
  [libunwind] [SEH] Initialize _msContext with RtlCaptureContext

When we initialize the UnwindCursor (unw_cursor_t) based on
an existing Registers object (unw_context_t), we only initialize
a subset of the class.

Fill the struct properly for the current thread with RtlCaptureContext,
followed by overwriting of the subset of registers that we do have
available in the Registers class.

One might think that it's enough to initialize specifically the
registers that we signal availability for with ContextFlags,
however in practice, that's not enough.

This fixes crashes when restoring the context via RtlRestoreContext
(via UnwindCursor::jumpto), via __unw_resume.
