* Instead of conditionalizing on the wrong preprocessor flag, now use
  the right one: LIBGCCJIT_HAVE_gcc_jit_context_add_driver_option

* Also perform the driver-option-adding step on win NT, but only if
  the function is non-NULL.

* Make the function declaration for add_driver_options non-old-style.

Add a customizable variable for driver options (such as linker flags)
to pass to libgccjit (Bug #42761).

* lisp/emacs-lisp/comp.el (comp-native-driver-options): New
customization variable.
* src/comp.c: Use comp-native-driver-options to set libgccjit's driver
options, if supported on the library's ABI version.

'dlopen' can return the same handle if two shared with the same
filename are loaded in two different times (even if the first was
deleted!).  To prevent this scenario the last modification time of the
source file is included in the hashing algorithm.

	* src/comp.c (Fcomp_el_to_eln_filename): Update hashing algo to
	include the source last modification date.
	* src/lread.c (maybe_swap_for_eln): Do not check for eln newer
	then elc as this is now unnecessary.
