print-rtl.c (print_rtx): Display the real-value equivalent of a const_double when easy.
* print-rtl.c (print_rtx): Display the real-value equivalent of
a const_double when easy.
* real.h (REAL_VALUE_TO_TARGET_SINGLE): Use a union to pun types.
Zero memory first for predictability.
(REAL_VALUE_TO_TARGET_DOUBLE): Likewise.
* varasm.c (immed_real_const_1): Notice width of H_W_I == double.
