On lowering from `memref` to LLVM, `malloc` and other intrinsic functions from `libc` will be declared in the current module. User's redefinition of these reserved functions will poison the internal analysis with wrong prototype. This patch adds assertion on the found function's type and reports if it mismatch with the intended type. Related to #120950 --------- Co-authored-by: Luohao Wang <Luohaothu@users.noreply.github.com>
