Fix maybe-uninitialized CodeView LF_INDEX warning
Initialize last_type to 0 to silence two spurious maybe-uninitialized
warnings.
We issue an LF_INDEX continuation subtype for any LF_FIELDLISTs that
overflow, so LF_INDEXes will always have a subtype preceding them (and
thus last_type will always be set).
gcc/
* dwarf2codeview.cc (get_type_num_enumeration_type): Initialize
last_type
to 0.
(get_type_num_struct): Likewise.
