Update demangler to GCC git 01d92cfd79872e4cffc78bf233bb9b767336beb8
Rust is moving to a new name mangling scheme:
https://github.com/rust-lang/rust/issues/60705. The libiberty demangler in GCC
has already been updated to support the new scheme so just update the copy in
Valgrind to match.
The update-demangler script has also been updated to use git instead of svn for
GCC.
There is a slight regression in that very long symbol names (> 512 bytes)
aren't demangled any more, but I don't feel that this is a big issue since all
other tools (binutils, c++filt, anything using libiberty) also suffers from
this issue.
