[rfc 6/8] record disas: omit function names by default

[markus.t.metzger@intel.com]

From: Markus Metzger <markus.t.metzger@intel.com>

Omit function names in the disassembly of the "record disassemble" command
unless the "/f" modifier is specified.

This helps align the disassembly output across functions.  The branch
destination is already obvious from the instruction order.

2013-02-14 Markus Metzger <markus.t.metzger@intel.com>

	* record.c (get_disas_modifiers): Set DISASSEMBLY_OMIT_FNAME
	unless /f is given.
	(_initialize_record): Update the "record disassemble" help text.
