[committed] vmsdbgout: Remove useless register keywords [PR100255]

[Jakub Jelinek]

Hi!

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

Tested with x86_64-linux -> ia64-hp-vms cross configured with
CXX='g++ -std=c++17', committed to trunk as obvious.

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