Log message:
	range stepping: gdbserver (x86 GNU/Linux)
	
	This patch adds support for range stepping to GDBserver, teaching it
	about vCont;r.
	
	It'd be easy to enable this for all hardware single-step targets
	without needing the linux_target_ops hook, however, at least PPC needs
	special care, due to the fact that PPC atomic sequences can't be
	hardware single-stepped through, a thing which GDBserver doesn't know
	about.  So this leaves the support limited to x86/x86_64.

	request to the lwp.
	(linux_supports_range_stepping): New.
