[PATCH] gas: drop sprint_value()

[Jan Beulich]

Its (documented) behavior is unhelpful in particular in 64-bit build
environments: While printing large 32-bit numbers in decimal already
isn't very meaningful to most people, this even more so goes for yet
larger 64-bit numbers. bfd_sprintf_vma() still tries to limit the number
of digits printed (without depending on a build system property), but
uniformly produces hex output.

	* as.h (sprint_value): Delete.
	* messages.c (sprint_value): Likewise.
	* config/tc-i386.c (offset_in_range): Use bfd_sprintf_vma in
	place of sprint_value.
	* config/tc-s390.c (s390_insert_operand): Likewise.
	* doc/internals.texi (sprint_value): Delete section.
	* write.c (fixup_segment): Likewise.
	(relax_segment): Likewise.
