35d6c41fde Fix part 1 of pr4682. PICADD is a 16-bit instruction even in thumb2 mode.

c00479253b Replace dregsingle operand modifier with explicit escaped curly brackets.
For other VLDn and VSTn operations, we need to list the multiple registers
explicitly anyway, so there's no point in special-casing this one usage.

fa2ea1a8cf Emit sub r, #c instead of transforming it to add r, #-c if c fits in 8-bit. This is a bit of pre-mature optimization. 8-bit variant makes it likely it will be narrowed to a 16-bit instruction.

3be03406c9 Normalize Subtarget constructors to take a target triple string instead of

Also, dropped uses of TargetMachine where unnecessary. The only target which
still takes a TargetMachine& is Mips, I would appreciate it if someone would
normalize this to match other targets.

d90183d25d Move the getInlineAsmLength virtual method from TAI to TII, where
the only real caller (GetFunctionSizeInBytes) uses it.

The custom ARM implementation of this is basically reimplementing
an assembler poorly for negligible gain.  It should be removed 
IMNSHO, but I'll leave that to ARMish folks to decide.

   sketchy. On the other hand, this particular usage is something of an idiom.
