* cse.c (cse_insn): Simplify REG_EQUAL note on libcalls when
making a substitution.
(dead_libcall_p): If directly replacing a libcall with a
constant value produces an invalid instruction, also try forcing
the constant into the constant pool.
* expr.c (emit_move_insn): Add a REG_EQUAL note when it is not
obvious that the source is a constant.
(compress_float_constant): Use set_unique_reg_note to place
REG_EQUAL notes on instructions.
