CppWriter::progname is never initialized but it is used in CppWriter::error(). 
This leads to a crash if error() is ever called.

Steps to Reproduce:
$ cat temp.ll
; x86_fp80 not supported by CppWriter
@x = common global x86_fp80 0xK00000000000000000000

$ llvm-as temp.ll
$ llc -march=cpp temp.bc


Actual Results:
Crash inside iostream

Expected Results:
Print "llc: Invalid primitive type"
