add support for .asciz, and enable it by default. If your target assemblerdoesn't support .asciz, just set AscizDirective to null in your asmprinter.

This compiles C strings to:
l1__2E_str_1: ; '.str_1'
.asciz "foo"
instead of:
l1__2E_str_1: ; '.str_1'
.ascii "foo\000"

add support for prefix/suffix strings to go around GlobalValue(s)

(which may or be function pointers) in the asmprinter. For the moment,
this changes nothing, except the IA64 backend which can use this to write:
data8.ua @fptr(blah__blah__mangled_function_name)
(by setting FunctionAddrPrefix/Suffix to "@fptr(" / ")")

prints:
getelementptr (int* %A, int -1)
as: "(A) - 4" instead of "(A) + 18446744073709551612", which makes the

This fixes test/Regression/CodeGen/X86/2005-02-14-IllegalAssembler.ll,
and Benchmarks/Prolangs-C/cdecl with LLC on X86.

Do not use .xword and friends to emit zeros on V9. Apparently there are issues
...
with emitting .xwords when not on an 8-byte boundary (.xword 0 is not the
same as 8 .byte 0's). Because we do not know when or when we are not aligned,
just emit bytes like the old V9 asmprinter did.
