[clang] remove dereferencing of invalid pointer
A line in the demangling code for float literals dereferences the
`.end()` iterator, which causes the Windows debug build of llvm-cxxfilt
to crash. The failure can be reproduced by passing the string
`_Z5dummyIXtl8wrapper1IdEtlNS1_Ut_Edi9RightNametlNS2_Ut_ELd405ec00000000000EEEEEEvv`
to `llvm-cxxfilt -n`.
This patch rewrites the code to use the `.size()` member of the
string_view type to avoid dereferencing past the buffer.
