- Rather than just constantly reprocess the binary representation, provide a structure (actually a union) that we can parse the binary representation into once at module load. This will boost performance
…nstructionIterator (definition)
…le_indices - br_table is the one instruction of variable length
- I had left in a few instructions breaking the code
… instead of []const u8
- That code parameter was used to calculate the continuations which is now down at decode time
- next returns RuntimeInstruction instead of ParseMeta
- we need this for generating a particular testsuite error (wrong number of br_table entries given, which actually ends up consuming some end 0x0b...it's not easy to differentiate this so let's just always check we can find the end of a function)

Purpose
Speed up execution by moving a bunch of work that is repeatedly performed during execution to the module loading stage
Description
Results
ReleaseSafeexecution time forfib(39)is reduced from around 80 s to around 30 s (putting us roughly on par with python)
