PATCH: Add "label::"

[H. J. Lu]

Intel ia64 assembler uses "label::" to indicate a global symbol. It
is same as

	.globl label
label:

This patch implements it for ia64. I can make it generic if it is
desired.

	* config/tc-ia64.c (ia64_check_label): New.
	* config/tc-ia64.h (tc_check_label): New.

	* read.c (read_a_source_file): Call tc_check_label after
	creating a user-defined label if defined.
