Merger of dmalcolm/jit branch from git

ChangeLog:
	* ChangeLog.jit: New.
	* MAINTAINERS (Various Maintainers): Add myself as jit maintainer.

contrib/ChangeLog:
	* ChangeLog.jit: New.
	* jit-coverage-report.py: New file: a script to print crude
	code-coverage information for the libgccjit API.

gcc/ChangeLog:
	* ChangeLog.jit: New.
	* Makefile.in (doc_build_sys): New variable, set to "sphinx" if
	sphinx is installed, falling back to "texinfo" otherwise.
	(FULL_DRIVER_NAME): New variable, adapted from the
	install-driver target.  New target, a symlink within the builddir,
	linked to "xgcc", for use when running the JIT library from the
	builddir.
	(MOSTLYCLEANFILES): Add FULL_DRIVER_NAME.
	(install-driver): Use $(FULL_DRIVER_NAME) rather than spelling it
	out.
	* configure.ac (doc_build_sys): New variable, set to "sphinx" if
	sphinx is installed, falling back to "texinfo" otherwise.
	(GCC_DRIVER_NAME): Generate a gcc-driver-name.h file containing
	GCC_DRIVER_NAME for the benefit of jit/internal-api.c.
	* configure: Regenerate.
	* doc/install.texi (--enable-host-shared): Specify that this is
	required when building libgccjit.
	(Tools/packages necessary for modifying GCC): Add Sphinx.
	* timevar.def (TV_JIT_REPLAY): New.
	(TV_ASSEMBLE): New.
	(TV_LINK): New.
	(TV_LOAD): New.
