This change adds support for the -fno-delayed-template-parsing option in
clang-cl.exe. This allows developers using clang-cl.exe to opt out of emulation
of MSVC's non-conformant template instantiation implementation while continuing
to use clang-cl.exe for its emulation of cl.exe command-line options. The
default behavior of clang-cl.exe (-fdelayed-template-parsing) is unchanged.
The MSVC Standard Library implementation uses clang-cl.exe with this switch in
its tests to ensure that the library headers work on compilers with the
conformant two-phase-lookup behavior.
