11208dcfb9 ARMv4 assembly pack: implement support for Thumb2. 
As some of ARM processors, more specifically Cortex-Mx series, are
Thumb2-only, we need to support Thumb2-only builds even in assembly.

c1669e1c20 Remove inconsistency in ARM support. 
This facilitates "universal" builds, ones that target multiple
architectures, e.g. ARMv5 through ARMv7. See commentary in
Configure for details.

2d22e08083 ARM assembler pack: reschedule instructions for dual-issue pipeline. 
Modest improvement coefficients mean that code already had some
parallelism and there was not very much room for improvement. Special
thanks to Ted Krovetz for benchmarking the code with such patience.
