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.

+
+# Documentation build hooks.
+#
+# The documentation can be built using the texinfo toolchain, or
+# the sphinx toolchain
+#
+# The jit documentation is authored using Sphinx, which has numerous
+# advantages over Texinfo, including:
+#
+#   * much faster
+#
+#   * use of CSS and JS to provide less of a 1990s feel in the generated
+#     HTML.
+#
+#   * sane, stable HTML page and anchor names
+#
+#   * sane HTML navigation: ability to move forward and back in the HTML
+#     at every node to read the HTML like a book
+#
+#   * syntax-coloring of examples
+#
+#   * the ability to "include" fragments of code inline.  This is used
+#     heavily by the jit docs, so that the example code is shared by both
+#     the test suite and the documentation to ensure that the examples
+#     appearing in the docs actually compile and work
+#
+# Sphinx is not a "blessed" dependency, and so a prebuilt libgccjit.texinfo
+# file built by Sphinx is checked into the source tree to avoid requiring
+# everyone to have Sphinx installed.
+#
+# This prebuilt libgccjit.texinfo has the "include" fragments "baked in",
+# and so contains the content from the sphinx toolchain, but lacks the
+# syntax-coloring, and the generated HTML is (IMHO) greatly inferior to
+# that generated by Sphinx.

+# These targets redirect HTML creation and installation to either
+# jit.sphinx.(install-)html or jit.texinfo.(install-)html.
