Disable my constant island pass optimization (to make use soimm more effectively). It caused infinite looping on lencod.

It's classifications now include elf-specific discriminators.  Targets
that don't have these features (like darwin and pecoff) simply treat
data.rel like data, etc.

Add a workaround for Darwin assembler bug where it's not setting the thumb bit in Thumb2 jumptable entries. We now pass Olden.

The later doesn't depend on any crazy LLVM IR stuff, and this
pulls the concatenation of prefix with GV name (the root problem behind
PR4584) out one level.

Correctly handle the Thumb-2 imm8 addrmode. Specialize frame index elimination more exactly for Thumb-2 to get better code gen.

testsuite, due to exception handling not working
correctly.  Maybe because the libgcc unwinder is
miscompiled - not sure, and I won't have time to
look into it before leaving on holiday.  Note that
miscompilations of libgcc are not picked up by the
nightly testers, because they dynamically link with
libgcc, so pick up the system version rather than
the version built as part of llvm-gcc.  This is a
nasty flaw in the nightly testers.  (On the other
hand the Ada testsuite links with the just built
libgcc).

Also fixed up code to fully use the SoImm field for ADR on ARM mode.
