[spirv] Better handling of constants.

We used to have multiple functions for creating constants. Now, we just
store the APFloat or APInt values. This makes the API much nicer. It
also removes the need for us to implement our own zero-extend and
sign-extend function (we can reuse llvm versions).

The main motivation behind this change, however, is to facilitate
Literal types:

If LiteralTypeVisitor visits an instruction and realizes that the result
type is a float, but it has a literal number argument that is a double,
it should use a float version of the literal number instead. In order to
do that, it CANNOT modify the constant directly because the constant
instruction is unique and is shared by other instructions.
Therefore, it will have to create a new constant of float type. It will
also have to go through the whole module and if there are no other
usages of the double literal, and if not, it should remove that constant
from the module.

Also, the constants used to use SpirvType. This meant that if the
LiteralTypeVisitor wanted to create a new constant, it would have to
investigate the resulting instruction's QualType and make decisions on
what kind of SpirvType to use for the new constant.

All of this is a lot of work and is inefficient.

With the new way of handling constants, we do not uniquify the constant
instructions in the SpirvBuilder. Any instruction that needs a constant
will get a brand new one.

Each constant is also only storing its QualType and APFloat/APInt value.

As a result, the LiteralTypeVisitor can easily update the QualType of
any constant instruction without worrying about affecting other
instructions. The update is also easy because it can simply reuse the
QualType that the literal type resolves to.

The LowerTypeVisitor pass will lower all QualType types of constants
into SpirvType.

The EmitVisitor pass will make sure there are no duplicate constants
(this is what the SpirvBuilder used to do).
