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.
