Fix non-blocking assignment to an array error state handling
...
If either the index or part offset expressions generate an undefined
value then the assignment is skipped. This patch reworks the code that
handles the flags used to detect this. For some simple cases a global
flag is not needed, but for other cases one is needed since there are
two expressions that can generate an error and even when there is only
a variable expression this error state needs to be preserved if there
is a variable delay. An undefined delay value defaults to zero and is
not an error.

vlog95: trim binary constants to save space and emit size of undef. consts.
...
This should not change the functionality, but to save space trim any
unneeded bits from a binary constant. Also for the case of emitting
a signed undefined value when the allow signed flag is not set add
the width to the constant.
