libiberty: Support the new ("v0") mangling scheme in rust-demangle
...
This is the libiberty (mainly for binutils/gdb) counterpart of
https://github.com/alexcrichton/rustc-demangle/pull/23 .
Relevant links for the new Rust mangling scheme (aka "v0"):
* Rust RFC: https://github.com/rust-lang/rfcs/pull/2603
* tracking issue: https://github.com/rust-lang/rust/issues/60705
* implementation: https://github.com/rust-lang/rust/pull/57967
This implementation includes full support for UTF-8 identifiers
via punycode, so I've included a testcase for that as well.
libiberty/ChangeLog:
* rust-demangle.c (struct rust_demangler): Add
skipping_printing and bound_lifetime_depth fields.
(eat): Add (v0-only).
(parse_integer_62): Add (v0-only).
(parse_opt_integer_62): Add (v0-only).

(demangle_const): Add (v0-only).
(demangle_const_uint): Add (v0-only).
(basic_type): Add (v0-only).
(rust_demangle_callback): Support v0 symbols.
* testsuite/rust-demangle-expected: Add v0 testcases.

libiberty: Add Rust symbol demangling.
...
Adds Rust symbol demangler. Rust mangles symbols using GNU_V3 style,
adding a hash and various special character subtitutions. This adds
a new rust style to cplus_demangle and adds 3 helper functions
rust_demangle, rust_demangle_sym and rust_is_mangled.
rust-demangle.c was written by David. Mark did the code formatting to
GNU style and integration into the gcc/libiberty build system and
testsuite.
