[Patch 1/2][ARM]Split insn type alu_reg into alu_sreg and alu_dsp_reg

["Terry Guo" <terry dot guo at arm dot com>]

Hi there,

Currently the insn type of DSP-kind instructions like QSUB8 is alu_reg which
is same as other normal instructions like SUB. In order to distinguish those
DSP-kind instructions, this patch intends to replace current alu_reg with
two sub categories alu_sreg and alu_dsp_reg. Meanwhile the alus_reg is
renamed to alus_sreg in terms of consistence. This is the first patch of
this series and intends to cover the files under gcc/config/arm. Tested with
gcc regression, no new regressions. Is it ok to trunk?

BR,
Terry
