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.

This removes all remnants of `@` pointers from rustc. Additionally, this removes
the `GC` structure from the prelude as it seems odd exporting an experimental
type in the prelude by default.

Issue #352Closes#1720
The old checker would happily accept things like 'alt x { @some(a) { a } }'.
It now properly descends into patterns, checks exhaustiveness of booleans,
and complains when number/string patterns aren't exhaustive.
All the files below had at least one instance of the ternary operator
present in the source. All have been changed to the equivalent
if/then/else expression.
3 tests, pretty/block-disambig.rs, run-pass/operator-overloading.rs,
and run-pass/weird-exprs.rs, all included the ternary operator. These
were changed to use the if-then-else construct instead.
2 tests, run-pass/block-arg-in-ternary.rs and run-pass/ternary.rs, were
only there because of the ternary operator, and were removed.
