wasm: Fix pointer to field of packed struct
...
When requesting a pointer to a field of a packed struct (of which is
not byte-aligned), we simply provide the address of the packed struct
itself.

wasm: support non-natural alignment in load/store
...
This implements support for loading and storing where the lhs is
of pointer type with host_size != 0. e.g. when loading a specific
field from a packed struct with a non-byte alignment such as (0:1:3).

wasm: airAggregateInit - Support packed structs
...
This allows the Wasm backend to construct an instance of a packed
struct during runtime. We first allocate a local, and then
shift+or each field's value into the result local. We then finally
return this result local as value.
The commit also fixes a type-issue in `airElemVal` where we used
the element type instead of a pointer type to store the value's
address into.

wasm: support passing packed struct over C-ABI
...
This also adds support loading a runtime pointer from a packed struct.
Also, this commit improves many utility functions such as `trunc` and
`intcast` to also support non-integer types such as booleans.

wasm: airStructFieldPtr - Support packed structs
...
Simplifies the airStructFieldPtr(index) functions to only obtain the
correct struct type and field index, which is then passed into the
structFieldPtr function. This function now calculates the byte-offset
of the field's address and returns a new `WValue` with this offset.
This means we only have to do this calculation in a single function,
and no longer have to duplicate any logic. This also handles both
regular (tagged) unions and packed unions.

wasm: airStructFieldVal - Support packed structs
...
This implements loading a field from a packed struct, regardless of
its field's type. This means it supports pointers, floats and
integers. The commit also extracts the logic from airTrunc into its
own `trunc` function so it can be re-used.

wasm: add support packed structs in lowerConstant
...
When lowering constants of packed structs, which are smaller than 65
bits, we lower the value to an integer rather than store it in the
constant data section. This allows us to use an immediate value,
for quick loads and stores.

We postpone emitting debug info until *after* we generate the function
so that we have an idea of the consumed stack space. The stack offsets
encoded within DWARF are with respect to the frame pointer `.fp`.
