eature--Single Step of KDB on xscale is on work

[LIAO, GUANGDENG]

HI all:
For personal interest.  I have tested the Feature¡ªSingle Step of KDB Patch on Xscale. And find it is good. 
Because of difference between Ia32 and Xscale Architecture. So I develop some new test suites to test it. As follows:
.macro COND_INS_LOGICAL bit_cond,ins,ins_cond,category1,category2,rd1,rd2,rs,shifter_operator
      mrs r0,cpsr
      and r0, r0, #MASK_NZCV
      orr r0, r0, #\bit_cond
      msr cpsr,r0
      .if \category1
      add r1,r15,#12
¡­¡­¡­¡­¡­¡­¡­.
If you want to test Single step, I will happy to give your Test suites to test it
