This commit merges in changes from branches/ASPACEM (specifically,
changes from r4341 through r4787 inclusive).  That branch is now dead.
Please do not commit anything else to it.

For the most part the merge was not troublesome.  The main areas of
uncertainty are:

- build system: I had to import by hand Makefile.core-AM_CPPFLAGS.am
  and include it in a couple of places.  Building etc seems to still
  work, but I haven't tried building the documentation.

- syscall wrappers: Following analysis by Greg & Nick, a whole lot of
  stuff was moved from -generic to -linux after the branch was created.
  I think that is satisfactorily glued back together now.

- Regtests: although this appears to work, no .out files appear, which
  is strange, and makes it hard to diagnose regtest failures.  In
  particular memcheck/tests/x86/scalar.stderr.exp remains in a 
  conflicted state.

- amd64 is broken (slightly), and ppc32 will be unbuildable.  I'll
  attend to the former shortly.
