Document quick_symbol_functions::expand_symtabs_matching invariant

While working on my series to replace the DWARF psymbol reader, I
noticed that the expand_symtabs_matching has an undocumented
invariant.  I think that, if this invariant is not followed, then GDB
will crash.  So, this patch documents this in the relevant spots and
introduces some asserts to make it clear.

Regression tested on x86-64 Fedora 32.
