  -----------
  [AMDGPU] Fix resource analysis crash on alias-to-alias function (#99034)

Summary:
Previously this code only looked through a single level of aliases to
find the underlying function. This patch changes it to continue until it
finds the end. Aliases that form a cycle are illegal IR, so we shouldn't
need to worry about infinite loops.
