vmsdbgout: Remove useless register keywords

register keyword was removed in C++17, and in vmsdbgout.c it served no
useful purpose.

2021-04-26  Jakub Jelinek  <jakub@redhat.com>

	PR debug/100255
	* vmsdbgout.c (ASM_OUTPUT_DEBUG_STRING, vmsdbgout_begin_block,
	vmsdbgout_end_block, lookup_filename, vmsdbgout_source_line): Remove
	register keywords.
