* config/arc/arc-protos.h (output_shift): Rename to...
(output_shift_loop): Tweak API to take an explicit rtx_code.
(arc_split_ashl): Prototype new function here.
(arc_split_ashr): Likewise.

(arc_split_rotl): Likewise.
(arc_split_rotr): Likewise.
* config/arc/arc.cc (output_shift): Delete local prototype. Rename.
(output_shift_loop): New function replacing output_shift to output
a zero overheap loop for SImode shifts and rotates on ARC targets
without barrel shifter (i.e. no hardware support for these insns).
(arc_split_ashl): New helper function to split *ashlsi3_nobs.
(arc_split_ashr): New helper function to split *ashrsi3_nobs.
(arc_split_lshr): New helper function to split *lshrsi3_nobs.

ashrsi3 and lshrsi3 define_expands. Adds rotlsi3 and rotrsi3.
(*<ANY_SHIFT_ROTATE>si3_nobs): New define_insn_and_split that
unifies the previous *ashlsi3_nobs, *ashrsi3_nobs and *lshrsi3_nobs.
We now call arc_split_<insn> in arc.cc to implement each split.
(shift_si3): Delete define_insn, all shifts/rotates are now split.
(shift_si3_loop): Rename to...
(<insn>si3_loop): define_insn to handle loop implementations of
SImode shifts and rotates, calling ouput_shift_loop for template.
(rotrsi3): Rename to...
(*rotrsi3_insn): define_insn for TARGET_BARREL_SHIFTER's ror.
(*rotlsi3): New define_insn_and_split to transform left rotates
into right rotates before reload.
(rotlsi3_cnt1): New define_insn_and_split to implement a left
rotate by one bit using an add.f followed by an adc.
