asm: Use .asciz and .ascii instead of .string

Browse source 
We use the .string pseudo-op both in some of our test assembly files
and in our -Oasm output.  We expect this to emit a \0 terminated
string into the .o file.  However for certain targets (e.g. HP
PA-RISC) it doesn't include the \0.  Use .asciz instead, which
explicitly does what we want.

There's also one place we can use .ascii (which explicitly emits a
string *without* \0 termination) instead of multiple .byte directives.
