choikwa 04db60d150 [AMDGPU] Prevent hang in SIFoldOperands by caching uses (#82099) ...

foldOperands() for REG_SEQUENCE has recursion that can trigger an infinite loop
as the method can modify the operand order, which messes up the range-based
for loop. This patch fixes the issue by caching the uses for processing beforehand,
and then iterating over the cache rather using the instruction iterator.
