Precompute hash value for symbol_set_names
We can also compute the hash for the mangled name on a background
thread so make this function even faster (about a 7% speedup).
gdb/ChangeLog:
2019-11-27 Christian Biesinger <cbiesinger@google.com>
* minsyms.c (minimal_symbol_reader::install): Also compute the hash
of the mangled name on the background thread.
* symtab.c (symbol_set_names): Allow passing in the hash of the
linkage_name.
* symtab.h (symbol_set_names): Likewise.
