insn_info::has_been_deleted () is documented to return true if an
instruction is deleted. Such instructions have their `volatile` bit set,
which can be tested via rtx_insn::deleted ().
The current condition for insn_info::has_been_deleted () is:
* m_rtl is not NULL: this can't happen as no member of insn_info
changes this pointer.
* !INSN_P (m_rtl): this will likely fail for rtx_insn objects and
does not test the `volatile` bit.
This patch drops these conditions and calls m_rtl->deleted () instead.
The impact of this change is minimal as insn_info::has_been_deleted
is only called in insn_info::print_full.
Bootstrapped and regtested x86_64-linux.
gcc/ChangeLog:
* rtl-ssa/insns.h: Fix implementation of has_been_deleted ().
