* emit-rtl.c (global_rtl): Update comment.
(const_double_htab, const_double_htab_hash,
const_double_htab_hash, lookup_const_double): New.
(const_int_htab_hash, const_int_htab_eq): Remove const
qualifiers, which cause tons of warnings with RTL checking on.

resemblance to the former immed_real_const_1.
(immed_double_const): Moved here from varasm.c and
simplified.
(gen_rtx_REG): Make REGNO unsigned to squelch warnings.
(gen_rtx_SUBREG): Use gen_rtx_raw_SUBREG.
(gen_rtx): Use immed_double_const.
(init_emit_once): Initialize the const_double_htab. Use
REAL_VALUE_FROM_INT where possible. Can now use
CONST_DOUBLE_FROM_REAL_VALUE when setting up const_tiny_rtx.

const_double_from_real_value, not immed_real_const_1, and use
it to define CONST_DOUBLE_FROM_REAL_VALUE. Define new macro
CONST_DOUBLE_ATOF.
