used-before-assignment false positive with nonlocal

[darintay]

Bug description

Getting a false positive for used-before-assignment in the latest pylint release when the variable is declared nonlocal. I don't think the new try/except logic is handling it correctly, I believe the code below is valid.

# pylint: disable=missing-docstring
def outer():
    myvar = 1
    def inner():
        nonlocal myvar
        try:
            print("A", myvar)
            raise IOError("emyvarc")
        except IOError:
            print("B", myvar)
            myvar += 1
            print("C", myvar)
    inner()
outer()
