When variable A references variable B, and B gets SSA-renamed, A also needs unique names even if A's expression text is identical across branches. Example: 1. parts = split(input, delim, 0); part1 = getAttr(parts, "[0]") 2. parts = split(input, delim, 1); part1 = getAttr(parts, "[0]") "parts" gets renamed to parts_ssa_1/parts_ssa_2, but "part1" wasn't being renamed despite referencing "parts". After rewriting, the expressions diverge, causing BDD validation failures.

Note the split model currently won't compile due to the bug fixed in smithy-lang#2946 Commiting so I can pull that change in and regenerate

When variable A references variable B, and B gets SSA-renamed, A also needs unique names even if A's expression text is identical across branches.
Example:
"parts" gets renamed to parts_ssa_1/parts_ssa_2, but "part1" wasn't being renamed despite referencing "parts". After rewriting, the expressions diverge, causing BDD validation failures.
