(float{,uns}sidf2): Call rs6000_float_const to portably build the proper floating point constant for conversions.

(float{,uns}sidf2): Call rs6000_float_const to portably build the proper
floating point constant for conversions.
(movdi): Properly handle movdi of CONST_{INT,DOUBLE} on little endian systems.

(output_option{,s}): New functions to write -f, -m, and -W options to the
asm file.
(rs6000_float_const): New function to generate floating point constants
portably used in signed,unsigned -> double conversions.
(rs6000_stack_info,debug_stack_info): Use ABI enumeration instead
of AIX vs. V.4 boolean.

From-SVN: r10317

(rs6000_stack): Use abi enum, not AIX vs. V.4 boolean.
(ASM_OUTPUT_OPTIONS): New macro to print output options in .s file.
(ASM_FILE_START): Use it.
(output_options,rs6000_float_const): Declare new functions.

(FLO_union_type): Remove bitfields to set sign, exponent, and
mantissa, and add value_raw field, which is an integer of the
appropriate type.  If _DEBUG_BITFLOAT is defined, provide little and
big endian bitfields.  If the macro FLOAT_BIT_ORDER_MISMATCH is
defined, use explicit bitfields.
(pack_d, unpack_d): Switch to use value_raw and explicit shifts and
masks so that we don't have to worry about whether the target is big
or little endian unless FLOAT_BIT_ORDER_MISMATCH is defined.  If
single precision floating point, rename to pack_f and unpack_f, so
there is no confusion in the debugger.
