[PATCH, gas] Use command line consistently in gas doc

[Thomas Preudhomme <thomas dot preudhomme at foss dot arm dot com>]

Hi,

c-aarch64.texi and c-arm.texi contain several occurrences of commandline
instead of "command line" which the rest of gas documentation seems to
have settled on. This patch changes these occurences for better
consistency.

ChangeLog entry is as follows:

*** gas/ChangeLog ***

2018-02-19  Thomas Preud'homme  <thomas.preudhomme@arm.com>

	* doc/c-aarch64.texi: Replace uses of "commandline" by "command line".
	* doc/c-arm.texi: Likewise.

Committed as obvious.

Best regards,

Thomas
