Since #29513, syntax errors in else and elif blocks, like:

if 1:
    pass
else:
    This is invalid syntax (sic)

are reported at the else:

  File "/tmp/repro.py", line 3
    else:
    ^^^^^^
SyntaxError: 'else' must match a valid statement here

This is quite unhelpful when a small typo is hiding in a large block.

@lysnikolaou, could you take a look?
