Previously this wouldn't have worked, since .first isn't a valid member.
The only reason it wasn't caught is because the function is never
instantiated.
This needs to divide by 8 to get a proper byte size for all type sizes.
The only usage of this is currently a uint64_t, so it worked by
coincidence, since sizeof(uint64_t) == 8.
Element size doesn't really mean anything here, considering all bits are
acted upon independently of segmentation.
Makes using these ops a little bit less noisy.
Most constants don't need to be padded for relocations. So now that
these have all been audited, switch to defaulting to NoPad to reduce
verbosity.
The number of constant that need to be explicitly padded are now marked
and with all the prior changes, this allows bisecting if something has
gone wrong.
Enables memcpy optimization of 80bit floats on reduced precision.
Also uncovered a bug where if we had done 80bit memcpy
optimization, we wouldn't have properly stored the 80bits.
This was caught by the existing tests when we enabled the optimization.
The InterpretAsFloat was never properly made use of. There's a couple of issues
that are fixed more easily with this gone, so lets remove it.
If there's a specific optimization that requires this, we can bring it back
at a later time. This should not have any effect on the current code generation.
Just a trivial rearrangement, Drops the struct down to 40 bytes.
We can also make some functions take it by const reference so we
aren't churning some copies.

Reduces a bunch of noise related to the register classes and hoists them
out so that converting the classes over to enums should be fairly
straightforward.
Instead of having this sort of odd indirection through a struct type,
we can add support for defining custom enums in the IR description.
This lets us both get strong typing (and allow for weak typing, should
any enum in the future need it), without needing a struct for a basic
value type.
Even then, if we do need a struct for anything in the future, then
we still allow strong typing for values themselves while allowing
them to be used in various ways.
This adds a new mode X87StrictReducedPrecision.
The strict reduced precision is like the reduced precision but adds extra checks,
like the currently implemented nan and snan propagations.
