* Fix apparently-long-standing bug in FloatIn
The float-in pass wasn't doing the right thing when you have
let x{rule mentions y} = rhs in body
It allowed a binding mentioning y to float into the body, which is
obviously wrong. I think this bug has been there a long time; I don't
really know why it has not come up before.
It showed up when compiling Text.Regex.Base.Context with WAY=p in
package regex-base.
