Allow symbol and label names to be enclosed in double quotes.

gas	PR gas/18581
	* expr.c (get_symbol_end): Rename to get_symbol_name.  Add a
	return parameter pointing to the start of the symbol.  Allow
	symbol names enclosed in double quotes.
	(restore_line_pointer): New function.  Replace the NUL character
	inserted into the input stream with the given character.  If the
	character was a double quote, advance the input pointer.
	* expr.h (get_symbol_end): Delete.
	(get_symbol_name): Add prototype.
	(restore_line_pointer): Prototype.
	* read.h (SKIP_WHITESPACE_AFTER_NAME): New macro.
	* doc/as.texinfo (Symbol Intro): Document that symbol names can
	now be enclosed in double quotes.
	* cond.c (s_ifdef): Replace get_symbol_end with get_symbol_name.
	Use restore_line_pointer to replace the NUL in the input stream.
	Use SKIP_WHITESPACE_AFTER_NAME to skip past the end of a symbol.
	Check for the use of double quoted symbol names.
