[PATCH] bitint: Fix handling of VIEW_CONVERT_EXPRs to minimally supported huge INTEGER_TYPEs [PR113783]

Hi! On the following testcases memcpy lowering folds the calls to reading and writing of MEM_REFs with huge INTEGER_TYPEs - uint256_t with OImode or uint512_t with XImode. Further optimization turn the load from MEM_REF from the large/huge _BitInt var into VIEW_CONVERT_EXPR from it to the
