gdb: Convert language la_pass_by_reference field to a method

Browse source 
This commit changes the language_data::la_pass_by_reference function
pointer member variable into a member function of language_defn.

The interesting thing in this commit is that I have removed the
default_pass_by_reference function entirely.  This function only ever
returned a language_pass_by_ref_info struct in its default state, so
all uses of this function can be replaced by just default
initialisation of a language_pass_by_ref_info variable.

There should be no user visible changes after this commit.

gdb/ChangeLog:

	* ada-lang.c (ada_language_data): Delete la_pass_by_reference
	initializer.

	(cplus_language::pass_by_reference_info): New method.
	(asm_language_data): Delete la_pass_by_reference initializer.
	(minimal_language_data): Likewise.
	* cp-abi.c (cp_pass_by_reference): Remove use of
	default_pass_by_reference.
