- -fpch-instantiate-templates tries to instantiate templates already while
generating a precompiled header. Such templates do not need to be
instantiated every time the precompiled header is used, which saves compile
time. This may result in an error during the precompiled header generation
if the source header file is not self-contained. This option is enabled
by default for clang-cl.
