Code review

Added a test, simplified another and added
a lot of TODO's.

 - Storing u8 in memory still claims 32 bits (since that's what you need in local variables). However, using load8_u / loadu_s we can optimize this.
 - Implement a FizzBuzz example
 - Also, check the codes for FIXME and TODO
+- Allocation is done using pointers for members, is this desired?
+
+- Merge in type classes
+
+- test_bitwise_or_inv_type
+- test_bytes_index_out_of_bounds vs static trap(?)
+- test_num.py is probably best as part of the generator?
+- Find pytest.mark.skip
+- There's a weird resolve_as reference in calculate_alloc_size
+  - Either there should be more of them or less
+  - At first glance, looks like failure in the typing system
+  - Related to the FIXME in phasm_type3?
+- WEBASSEMBLY_BUILTIN_FLOAT_OPS and WEBASSEMBLY_BUILTIN_BYTES_OPS are special cased
+  - Should be part of a prelude
+- Casting is not implemented except u32 which is special cased
+- Parser is putting stuff in ModuleDataBlock
+  - Compiler should probably do that
