r280104 - Disable clang/test/SemaTemplate/instantiation-depth-default.cpp temporarily for targeting mingw32. It crashes. Investigating.

[NAKAMURA Takumi via cfe-commits]

Thanks, Richard.

Conversely, do we need to give sufficient amount of stack to the clang
executable whenever this fails?

By default, clang.exe has 2MiB (and *-tblgen.exe(s) are gaven 16MiB) of
stack on mingw-w64. 10,000,000 bytes on MS-compiled executables. I can
easily increase the size.
See HandleLLVMOptions.cmake and TableGen.cmake.
