PowerPC reorg and support for powerpc64-*-linux*.
Also fixes emitting of constants on 32 bit and 64 bit
platforms.
* config.gcc: powerpc64-*-linux* is a new target.
Things that needed aix.h now also include xcoff.h
* config/rs6000/rs6000.h: Split XCOFF specific stuff into
xcoff.h.
Move AIX specific stuff into aix.h.
(ASM_LONG): Use DOUBLE_INT_ASM_OP if we are on a 64 bit target.
(ASM_OUTPUT_DOUBLE_INT): Ditto.
(TARGET_AIX): Renamed to TARGET_XCOFF, since the AIX ABI is used
with more than just XCOFF now.
(SET_ASM_OP): Remove, now defined where needed.
(FUNCTION_PROLOGUE): New macro definition.
(FUNCTION_EPILOGUE): New macro definition.
(CONST_OK_FOR_LETTER_P): Change N to require that value is
positive, too.
(ASM_OPEN_PAREN, ASM_CLOSE_PAREN): New macro definition.
(PREDICATE_CODES): Added exact_log2_cint_operand,
reg_or_add_cint64_operand, reg_or_sub_cint64_operand.
* config/rs6000/rs6000.c: #ifdef XCOFF debugging info stuff on
XCOFF_DEBUGGING_INFO.
Use DOUBLE_INT_ASM_OP where approriate.
(rs6000_emit_set_long_const): New function.
(rs6000_emit_set_const): New function.
(reg_or_sub_cint64_operand): New function.
(reg_or_add_cint64_operand): New function.
(exact_log2_cint_operand): New function.
* config/rs6000/rs6000.md: Fix emitting of constants.
Fix patterns that were AIX ABI specific, but depended on
!TARGET_ELF (instead of DEFAULT_ABI == ABI_AIX).
* config/rs6000/xcoff.h: New file.
* config/rs6000/linux64.h: New file.
* config/rs6000/darwin.h: Copy needed AIX alignment definitions.

cp:
The 3.0 ABI no longer has vbase pointer fields.

FORMAT_VBASE_NAME): Remove.
* method.c (do_build_copy_constructor): Adjust.
(do_build_assign_ref): Adjust.
* search.c (lookup_field_r): Adjust.
* typeck.c (build_component_ref): Adjust.
The 3.0 ABI always has a vtable pointer at the start of every
polymorphic class.
* rtti.c (build_headof_sub): Remove.
(build_headof): Adjust.
(get_tinfo_decl_dynamic): No need to check flag_rtti
here. Adjust.
(create_real_tinfo_var): Explain why we need a hidden name.
