Log Message:
-----------
report uninit variable name even in optimized cases
Several cases that used to be simple assignment ops with lexical
variables have been optimized in some way:
- $foo = undef is now a single OP_UNDEF with special flags
- $foo = ... is now a single OP_PADSV_STORE
- $foo[0] = ... is now a single OP_AELEMFASTLEX_STORE
This is mostly transparent to users, except for "Use of uninitialized
value" warnings, which previously mentioned the name of the undefined
variable, but don't do so anymore in blead.
This commit teaches find_uninit_var() about the new ops, so error
messages for these ops can mention variable names again.
Fixes #20945.
