Remove TrustedLen requirement from BuilderMethods::switch
12ada5c 
The main use case of TrustedLen is allowing APIs to specialize on it,
but no use of it uses that specialization. Instead, only the .len()
function provided by ExactSizeIterator is used, which is already
required to be accurate.

Thus, the TrustedLen requirement on BuilderMethods::switch is redundant.

Add const_fn_floating_point_arithmetic
0d2521a
@ecstatic-morse
Put floating point arithmetic behind its own feature gate
2049052 
This refactors handling of `Rvalue::{Unary,Binary}Op` in the
const-checker. Now we `span_bug` if there's an unexpected type in a
primitive operation. This also allows unary negation on
`char` values through the const-checker because it makes the code a bit
cleaner. `char` does not actually support these operations, and if it
did, we could evaluate them at compile-time.

Rename whence to span
aa6a2f4 
It's called `span` elsewhere in the compiler and `span` is also less
surprising. `whence` is whimsical, but not super clear :)
