HLSL doesn't support bitcasting a 64bit integer to a double. DXIL
doesn't have generic pack/unpack instructions, so we lower those to
integer bitwise ops. As a result, NIR generic double pack/unpack would
require our backend to emit a bitcast to get a double, but we want
to match HLSL semantics and emit MakeDouble/SplitDouble.
Adding a dedicated opcode for double pack/unpack allows us to add a
pass to emit that instead, which lets our backend emit the right
instruction to pack and unpack doubles.

Helps deduplicate some code between the two lowering paths. In
particular, it ports the missing 32-bit? check to the precise pass. This
does not change anything immediately: drivers depending on this to lower
16-bit did not work before due to type mismatches and will not work now
since it'll refuse to lower. But that means sub-32-bit idiv can be
lowered more efficiently in an algebraic pass.

When packing varyings when there is only 32bit of space
left in slot 64bit type is attempted to be divided between
current and next slot. However there is neither code for
splitting the 64bit type nor for assembling it back.
Instead we add 32bit padding.
The above happens only in structs because their
members aren't sorted by packing order.
Example of the issue:
struct S {
vec3 a;
double d;
};
out flat S s;
Before, the packing went as:
slot 32b 32b 32b 32b
0 a.x a.y a.z d
1 d 0 0 0
After:
slot 32b 32b 32b 32b
