Simon Marchi d82b3862f1 compile: Remove non-const reference parameters
As mentioned here:

  https://sourceware.org/gdb/wiki/Internals%20GDB-C-Coding-Standards#Avoid_non-const_reference_parameters.2C_use_pointers_instead

we prefer to avoid non-const references.  This patch changes the
non-const references I could find in the compile/ directory, either by
making them rvalue-reference (&&) or changing them to pointers.

I'd say all the changes are pretty obvious, except the one in
compile_cplus_instance::enter_scope which might require more attention.

gdb/ChangeLog:

	* compile/compile-c.h (generate_c_for_variable_locations):
	Change reference to pointer.
	* compile/compile-c-support.c (compile_program) <compute>:
	Likewise.
	* compile/compile-c-symbols.c (generate_vla_size): Likewise.
	(generate_c_for_for_one_variable): Likewise
	(generate_c_for_variable_locations): Likewise
	* compile/compile-c-types.c (compile_c_instance::convert_type):
	Likewise
	* compile/compile-cplus-symbols.c (convert_one_symbol):
	std::move the scope passed to enter_scope.
	* compile/compile-cplus-types.c
	(compile_cplus_instance::enter_scope): Make parameter
	rvalue-reference.
	(compile_cplus_instance::new_scope): Change reference to
	pointer.
	(compile_cplus_instance::convert_type): Likewise
	(compile_cplus_convert_typedef): std::move the scope passed to
	enter_scope.
	(compile_cplus_convert_struct_or_union): Likewise.
	(compile_cplus_convert_enum): Likewise.
	(compile_cplus_convert_namespace): Likewise.
