[ARM][cleanup] Use R0_REGNUM and R1_REGNUM instead of 0 and 1 where appropriate
* config/arm/arm.c (arm_load_tp): Use R0_REGNUM instead of constant 0
in gen_rtx_REG.
(arm_tls_descseq_addr): Likewise.
(arm_gen_movmemqi): Likewise.
(arm_expand_epilogue_apcs_frame): Likewise.
(arm_expand_epilogue): Likewise.
(arm_expand_prologue): Likewise. Use R1_REGNUM instead of constant 1
in gen_rtx_REG.
