[RFC PATCH 1/5] RISC-V: Use bool on riscv_set_options members

[Tsukasa OI <research_trasio@irq.a4lg.com>]

All uses of riscv_set_options members are safe to be bool.  If we change
them from `int' to `bool', we can shrink the `riscv_set_options' and the
intent of the members are clearer.

gas/ChangeLog:

	* config/tc-riscv.c (struct riscv_set_options): Make all members
	from `int' to `bool'.
