Fix a bug in petdr's recent changes to string__format that
broke things in non-gc grades on sparcs.

runtime/mercury_string.c:
	In MR_make_string(), wrap calls to restore/save_transient_hp()
	around the call to MR_make_aligned_string_msg(), as mentioned
	in the documentation for MR_make_aligned_string_msg().

runtime/mercury_string.h:
	Document that calls to MR_make_string need to be wrapped inside
	calls to save/restore_transient_hp().

library/string.m:
	Wrap calls to MR_make_string inside calls to
	save/restore_transient_hp().
