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

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

FLDD, FLDS, FCPYD, FCPYS, FSTD, FSTS, VMOVD, VMOVQ maps to the same instructions on all sub-targets.

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

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

Since we have moved unified assembly, switch to ADR instruction instead of a the difficult-to-read .set + add syntax to materialize pc-relative address.

Turns out this also fixed a poor code selection on Thumb1. I have no idea why we were using a mov + add to do the same thing as ADR before.

Fix frame index elimination to correctly handle thumb-2 addressing modes that don't allow negative offsets. During frame elimination convert *i12 opcode to a *i8 when necessary due to a negative offset.

Add R12 to the list of registers clobbered by 16-bit Thumb calls as a pre-caution. r12 could be live once we have mixed 32-bit and 16-bit instructions.

pool entry will require relocations against it.  I implemented this
conservatively for ARM, someone who is knowledgable about it should
see if this can be improved.

"private" symbols which the assember shouldn't strip, but which the linker may
remove after evaluation. This is mostly useful for Objective-C metadata.

This is plumbing, so we don't have a use of it yet. More to come, etc.
