alexcrichton opened PR #9136 from alexcrichton:i128-opts to bytecodealliance:main:

This commit implements a few minor changes for i128 in both the egraph optimizations and lowerings for x64. The optimization pass will now transform iconcat into a uextend or sextend where appropriate. The x64 backend then pattern-matches this to produce slightly more optimal machine code. Additionally the x64 backend now handles memory/immediate operands a bit better when the argument to a 128-bit operation is an iconcat.
