+def int_asan_check_memaccess :
+  Intrinsic<[],[llvm_ptr_ty, llvm_i8_ty, llvm_i8_ty],
----------------
PTAL at lvm.read_register.i32

How about:

llvm.asan.check.memaccess ->
  lvm.asan.check_read
  lvm.asan.check_write
  lvm.asan.kernel.check_read
  lvm.asan.kernel.check_write

Even better
  lvm.asan.check_read.{i8, i16, i32, ...}
  lvm.asan.check_write.{i8, i16, i32, ...}
  lvm.asan.kernel.check_read.{i8, i16, i32, ...}
  lvm.asan.kernel.check_write.{i8, i16, i32, ...}
