Fix Thumb2 function call isel. Thumb1 and Thumb2 should share the same
...
instructions for calls since BL and BLX are always 32-bit long and BX is always
16-bit long.
Also, we should be using BLX to call external function stubs.

The attached patches implement most of the ARM AAPCS-VFP hard float
...
ABI. The missing piece is support for putting "homogeneous aggregates"
into registers.
