DecodeInt33AsInt64 is a special cased decoder for wasm.BlockType which is encoded as a positive signed integer, yet still needs to fit the 32-bit range of allowed indices.

EncodeInt32 encodes the signed value into a buffer in LEB128 format See https://en.wikipedia.org/wiki/LEB128#Encode_signed_integer.

EncodeInt64 encodes the signed value into a buffer in LEB128 format See https://en.wikipedia.org/wiki/LEB128#Encode_signed_integer.
