<title>hashx: Cleanup around Instruction and NUM_INSTRUCTIONS</title>

<id>urn:sha1:2cb50d1be35a4a6623ff318fcf8ac2620521bb1f</id>
<content type='text'>
This patch tries to make some of the expressions around NUM_INSTRUCTIONS
more convenient. We can import it directly where it's needed, but most
uses are replaced by new type aliases for InstructionArray and
InstructionVec.

No change to any hashx_cachegrind iai benchmarks

<title>hashx: Avoid memcpy in Assembler::finalize()</title>

<id>urn:sha1:9d081f70363cac0a8de073588cf75f6870153dee</id>
<content type='text'>
This is a very simple change, just passing 'self' by reference instead of
value. The by-value version generates a memcpy of the entire temporary
program buffer which doesn't optimize out like I expected it would.

The juicy impact here is a much lower cache footprint for compilation,
since we avoid having yet another temporary storage location for the program
data.
