[PATCH] Remove bare 'throw' expression that breaks -fno-exceptions build

[Jonathan Wakely]

This is debugging code that wasn't meant to be left in, and prevents
building the filesystem TS library with -fno-exceptions. It was already
removed from trunk months aog, this removes it from the branch too.

	* src/filesystem/std-path.cc (path::remove_filename()): Remove debug
	check that prevents building with -fno-exceptions.

Thanks to Uri Simchoni for reporting it.

Tested x86_64-linux, committed to gcc-8-branch.
