Add builtins for basic float operations (#3897)

Browse Source 
Adds support for unary `-` and binary `+`, `-`, `*`, `/` for floating
point types.

Real literals are now transformed to `llvm::APFloat`s during the check
phase into the `FloatLiteral` instruction.

This PR likely collides a bit with #3892 and might need to be updated
when that one is merged.
