I'd like to merge the JIT branch into trunk:

This is "v2" since it incorporates fixes for the various issues
identified by Joseph in an earlier submission:
https://gcc.gnu.org/ml/gcc-patches/2014-09/msg02056.html
I've split up the current diff between trunk and the branch into 5
areas for ease of review (and to allow for early merger of the
supporting work, if it's deemed ready):
patch 1: exposes an entrypoint in libiberty that I need
patch 2: configure and Makefile changes in "gcc"
patch 3: timevar.h: Add an auto_timevar class
patch 4: State cleanups in "gcc"
patch 5: Add the "jit" code itself
[this is a diff of trunk r215958 aka
e012cdc775868e9922f5fef9068a764546876d93 which is from 2014-10-06,
vs jit branch version 75b3ee7acdc6de55354d65bb7d619386463e50a1].
I've successfully bootstrapped and regression-tested the cumulative
result of all of the patches against a control build, building them
both with --enable-host-shared, and with
--enable-languages=c,c++,objc,obj-c++,java,fortran,ada,go,lto
adding ",jit" to the test build (both on x86_64-unknown-linux-gnu;
Fedora 20).
There were no regressions vs the control build, and the patched build
gains a jit.sum, with 4663 passes (and no failures).
OK for trunk?
Patch 5 seems to have been too large, even compressed, so I'm breaking
it up into separate pieces and compressing, giving 10 patches in total
Patches 1-4 are as above.
Patch 5: remaining JIT-related changes outside of the gcc/jit/ subdir
Patch 6: the core of the JIT implementation: the gcc/jit subdir
Patch 7: the testsuite: gcc/testsuite/jit.dg
Patch 8: sphinx-based documentation: the gcc/jit/docs subdir
Patch 9: texinfo documentation autogenerated from the sphinx sources.
Patch 10: the ChangeLog.jit logs from the branch.
