(float) fix some rounding errors when showing as str
...
This seems to fix issue #1876 , and some of the superficial parts of
issue #1375 . The #fmt macro and the to_str functions will round,
rather than truncate, floats as strings.
Other issues remain, and I wrote more code here than intended, but the
following should pass now.
```
fn x() {
assert "3.1416" == #fmt["%.4f", 3.14159];
assert "3" == #fmt["%.0f", 3.14159];
assert "99" == #fmt["%.0f", 98.5];
assert "7.0000" == #fmt["%.4f", 6.999999999];
assert "3.141590000" == #fmt["%.9f", 3.14159];
}
```

Disallow rebinding / matching against consts in alts
...
As per Issue #1193 . Closes #1193 .
I had to rename a few variables ("info" and "epsilon") to avoid
clashing with in-scope constants, which is responsible for all the
changes other than resolve and issue-1193.rs.
