[3.8] bpo-32912: Revert SyntaxWarning on invalid escape sequences (GH-15142)
...
* bpo-32912: Revert warnings for invalid escape sequences.
DeprecationWarning will continue to be emitted for invalid escape sequences in string and bytes literals in 3.8 just as it did in 3.7.
SyntaxWarning may be emitted in the future. But per mailing list discussion, we don't yet know when because we haven't settled on how to do so in a non-disruptive manner.

If a "=" is specified a the end of an f-string expression, the f-string will evaluate to the text of the expression, followed by '=', followed by the repr of the value of the expression.

Additionally show that a backslash-escaped opening brace is treated as a literal and thus triggers the single closing brace error, clarifying #28590 .

Add an additional test with a newline, one that's very similar to test_parens_in_expressions, but because the newline is not a literal newline, but a backslash en, this error is triggered.

Closes issue 27921: Disallow backslashes anywhere in f-strings. This is a temporary restriction. In 3.6 beta 2, the plan is to again allow backslashes in the string parts of f-strings, but disallow them in the expression parts.

Move f-string compilation of the expression earlier, before the conversion character and format_spec are checked. This allows for error messages that more closely match what a user would expect.
