patch 9.1.0529: silent! causes following try/catch to not work
Problem: silent! causes following try/catch to not work
(Malcolm Rowe)
Solution: consider emsg_silent in handle_did_throw() and do not abort
evaluation flow for :silent! (LemonBoy)
The silent! flag causes the evaluation not to be aborted in case of
uncaught exceptions, adjust handle_did_throw to take this detail into
account.
Fixes the long-standing todo.txt item:
```
Problem that a previous silent ":throw" causes a following try/catch not
to work. (ZyX, 2013 Sep 28) With examples: (Malcolm Rowe, 2015 Dec 24)
Also see #8487 for an example.
```
fixes: #538
closes: #15128
