- Added support for compiler option `-x cuda`, understood by Clang.

- The value of the `SOURCE_DATE_EPOCH` variable is now only hashed if it
potentially affects the output from ccache. This means that ccache now (like
before version 4.0) will be able produce cache hits for source code that
doesn't contain `__DATE__` or `__TIME__` macros regardless of the value of
`SOURCE_DATE_EPOCH`.

- Fixed a bug where a non-Clang compiler would silently accept the
Clang-specific `-f(no-)color-diagnostics` option when run via ccache. This
confused feature detection made by e.g. CMake.
