floating point numbers for real.
This will break code that looks like:
let mut x = 0;
while ... {
x += 1;
}
println!("{}", x);
Change that code to:
let mut x = 0i;
while ... {
x += 1;
}
println!("{}", x);
Closes #15201.

syntax: desugar a `for` loop to a let binding to get better error2014-05-26T23:24:37+00:00Huon Wilsondbau.pp+github@gmail.com2014-05-26T12:01:09+00:00urn:sha1:f2a137829e07505aaaa2be4ae97d6ecfb6ef6823
messages when the pattern is refutable.
This means the compiler points directly to the pattern and said that the
problem is the pattern being refutable (rather than just saying that
some value isn't covered in the `match` as it did previously).
Fixes #14390.
