bpo-28307: Convert simple C-style formatting with literal format into f-string. (GH-5012)
C-style formatting with literal format containing only format codes
%s, %r and %a (with optional width, precision and alignment)
will be converted to an equivalent f-string expression.
It can speed up formatting more than 2 times by eliminating
runtime parsing of the format string and creating temporary tuple.

bpo-28307: Tests and fixes for optimization of C-style formatting (GH-26318)
Fix errors:
* "%10.s" should be equal to "%10.0s", not "%10s".
* Tuples with starred expressions caused a SyntaxError.
