[CMake] enable -fpch-instantiate-templates
https://bugs.webkit.org/show_bug.cgi?id=314020
rdar://176212395
Reviewed by Keith Miller.
~7s / 7% measured speedup on JavaScriptCore build time. (Projected
~19s speedup on full build time.)
-fpch-instantiate-templates allows a precompiled header to cache
the *instantiated* version of a template rather than the *parsed*
version. That way, .cpp files that include the precompiled header
don't need to instantiate.
* Source/cmake/WebKitCompilerFlags.cmake: Turn on
-fpch-instantiate-templates. (It's disabled by default in CMake
because of a funky version number workaround from like a decade
ago, which never got removed.)
