On ARM, use relocation_model to detect whether r9 should be reserved
...
The previous approach of checking for the reserve-r9 target feature
didn't actually work because LLVM only sets this feature very late when
initializing the per-function subtarget.

asm: Allow the use of r8-r14 as clobbers on Thumb1
...
Previously these were entirely disallowed, except for r11 which was
allowed by accident.

Pass target_features set instead of has_feature closure
...
This avoids unnecessary monomorphizations in codegen backends

...
This saves a couple of Symbol::intern calls

Add clobber-only register classes for asm!
...
These are needed to properly express a function call ABI using a clobber
list, even though we don't support passing actual values into/out of
these registers.

They are still allowed on x86 though.
