This is a bit nasty, mainly because Type.onePossibleValue is now
errorable, which is a quite viral change.

Sema: update core comptime detection logic to be InternPool aware
...
* Add some assertions to make sure instructions are not none. I tested
all these with master branch as well and made sure the behavior tests
still passed with the assertions intact (along with a handful of
callsite updates).
* Fix Sema.resolveMaybeUndefValAllowVariablesMaybeRuntime not noticing
that interned values are comptime-known. This was causing all kinds
of chaos.
* Fix print_air writeType calling tag() without checking for ip_index

InternPool: enhance integer values
...
The Key struct now has a Storage tagged union which can store a u64,
i64, or big int.
This is needed so that indexToKey can be implemented for integers stored
compactly in the data structure.

stage2: start the InternPool transition
...
Instead of doing everything at once which is a hopelessly large task,
this introduces a piecemeal transition that can be done in small
increments at a time.
This is a minimal changeset that keeps the compiler compiling. It only
uses the InternPool for a small set of types.
Behavior tests are not passing.
Air.Inst.Ref and Zir.Inst.Ref are separated into different enums but
compile-time verified to have the same fields in the same order.
The large set of changes is mainly to deal with the fact that most Type
and Value methods now require a Module to be passed in, so that the
InternPool object can be accessed.

os/plan9: fix order of register setting in syscall1
...
We need to set rbp last because the arguments are stored on the
stack. If we clobber rbp first, then we will get a segfault when
trying to access the function arguments.
I believe I had already done this with the other syscall* functions,
but not with syscall1, so this allows single argument syscalls like
close to work.
