[PATCH 2/5] RISC-V: Complete tidying up with SCALL and SBREAK

[Tsukasa OI]

This commit removes SCALL and SBREAK-related references except
alias opcode entries because they are renamed to ECALL and EBREAK
(respectively).

include/ChangeLog:

	* opcode/riscv-opc.h (MATCH_SCALL, MASK_SCALL, MATCH_SBREAK,
	MASK_SBREAK): Remove.  Also remove corresponding DECLARE_INSN
	declarations.

opcodes/ChangeLog:

	* riscv-opc.c (riscv_opcodes): Use `ebreak' instead of `sbreak'.

ChangeLog:

	* sim/riscv/sim-main.c (execute_i): Use `ebreak' instead of
	`sbreak'.
