[PATCH, AArch64 0/7] TImode and longlong.h improvements

[Richard Henderson <rth at redhat dot com>]

The recent longlong.h patch 

  http://gcc.gnu.org/ml/gcc-patches/2014-01/msg00286.html

reminded me that the other common patterns really ought to be supported
somehow.  We had patterns defining ADDS, ADC, and UMULH, but we didn't
have the proper expanders in place to make use of them.

The final longlong.h patch has nothing that's really aarch64 specific,
but I chickened out in making the generic patterns use builtin double
word arithmetic.  Perhaps some define set in the cpu-specific portion
of the file ought to select this from the final common portion, but
that sort of thing begs the question of large-scale cleanup.
