Abstract out operations specific to particular C++ ABI's, and invoke them through a function table. This removes the C++ ABI dependencies scattered throughout the code, and allows us to cleanly add support for new C++ ABI's. * cp-abi.h, cp-abi.h, gnu-v2-abi.c, hpacc-abi.c: New files. * c-typeprint.c, c-valprint.c, dbxread.c, eval.c, gdbtypes.c, jv-typeprint.c, linespec.c, symtab.c, typeprint.c, valops.c: #include "cp-abi.h". These files all use functions now declared there. * symtab.h (OPNAME_PREFIX_P, VTBL_PREFIX_P, DESTRUCTOR_PREFIX_P): Deleted. These services are now provided by functions declared in cp-abi.h. * value.h (value_rtti_type, value_virtual_fn_field): Same. * values.c (value_virtual_fn_field): Same, for this definition. * valops.c (value_rtti_type): Same. * c-typeprint.c (c_type_print_base): Use the functions from "cp-abi.h", instead of the old macros, or hard-coded ABI-specific tests. * dbxread.c (record_minimal_symbol): Same. * gdbtypes.c (get_destructor_fn_field, virtual_base_index, virtual_base_index_skip_primaries): Same. * jv-typeprint.c (java_type_print_base): Same. * linespec.c (find_methods, decode_line_1): Same. * symtab.c (gdb_mangle_name): Same. * Makefile.in (SFILES): Add the new .c files mentioned above. (cp_abi_h): New variable. (COMMON_OBS): Add gnu-v2-abi.o, hpacc-abi.o, and cp-abi.o. (cp-abi.o, gnu-v2-abi.o, hpacc-abi.o): New targets. (c-typeprint.o, c-valprint.o, dbxread.o, eval.o, gdbtypes.o, jv-typeprint.o, symtab.o, linespec.o, typeprint.o, valops.o): Add dependency on $(cp_abi_h).
