[Bug testsuite/29307] New: libiberty/testsuite/test-demangle : parsing errors after unknown demangling style

["phil dot lello at homecall dot co dot uk" <gcc-bugzilla at gcc dot gnu dot org>]

When running libiberty/testsuite/test-demangle with an unknown demangling
style, parsing gets confused...

NOTE: I came accross this while investigating adding support for vc-style
mangling to libiberty, so failure is expected, but the "unknown demangling
style" for lines other than the "--format=msvc" is misleading.

Input:
# Symbols from C:\WINDOWS\$hf_mig$\KB896358\SP2QFE\hhsetup.dll
--format=msvc --no-params
??0CFIFOString@@QAE@XZ
public: __thiscall CFIFOString::CFIFOString(void)
CFIFOString::CFIFOString
#
--format=msvc --no-params
??0CPointerList@@QAE@XZ
public: __thiscall CPointerList::CPointerList(void)
CPointerList::CPointerList

Output:
FAIL at line 4: unknown demangling style msvc
FAIL at line 4, options --format=msvc:
in:  ??0CFIFOString@@QAE@XZ
out: (null)
exp: public: __thiscall CFIFOString::CFIFOString(void)
