[pushed] [gdb/symtab] Revert "Add assert in free_cached_comp_units constructor"

[Tom de Vries <tdevries@suse.de>]

This reverts commit b083976272bd663ed036692e54796870b3bf6c89.

The new assert triggers in test-cases gdb.ada/uninitialized-variable-record.exp and
gdb.ada/uninitialized_vars.exp on x86_64-linux.
