When reading string arguments for the assembler's string directives treat space separated strings as a single entity.
* read.c (stringer): Treat space separated, quote enclosed strings
as a single string.
* doc/as.texi (asciz): Mention this behaviour in the description
of the asciz directive.
* testsuite/gas/all/asciz.s: New test.
* testsuite/gas/all/asciz.d: New test driver.
* testsuite/gas/all/gas.exp: Run the new test.
