Commit GSI patches from Wesley Terpstra
- Add JTAG capture pin
==> allows removing sensitivity to reg_update which caused clocking problems making JTAG unstable
- Use register file backed by RAM blocks
==> saves quite some area and speed on altera
... be sure to enable it using `define CFG_EBR_POSEDGE_REGISTER_FILE
- Fix a minor problem where compilation fails when interrupts are not supported
- Add support to flush icache and dcache per JTAG
- Fix wrong width assignments for PC
Multiplier patch has been left out for now; don't the design synthesizers (Quartus / Xst) split the multiply automatically?
