Detail: hdr/Macros - DivRem is now able to use UDIV when building for architectures that support it. A "norem" option is also available, to allow the remainder calculation to be skipped if it's not needed (since we don't get it for free when using UDIV). hdr/CPU/Generic32 - PHPSEI, WritePSRc and SetMode now use the ARMv6 CPS instruction where possible, delivering performance gains compared to the equivalent MSR. Where CPS isn't used, WritePSRc now attempts to emit a single MSR instead of the 4 instructions generated by the SCPSR macro. Admin: Tested on Cortex-A15 PSR manipulation macros trialed on a few different CPU architectures to arrive at the conclusion that CPS is as good or better than MSR Version 2.60.
