* dis-asm.h (struct disassemble_info): Add new field
'symbol_is_valid' which is a function which can tell the
disassembler to skip certain symbols as they should not be
displayed to the user.
(arm_symbol_is_valid): New prototype. This is the ARM
specific function for the symbol_is_valid field.
(generic_symbol_is_valid): New prototype. This is the default
function pointed to by the symbol_is_valid field.
