+Subject: [PATCH] IR builder: get rid of getPointerElementType calls
+
+Usage of Value::getPointerElementType is deprecated and will be dropped
+in LLVM 16 [1].
+
+There are several places where we use this method:
+- function (value) calls - the called function type is usually
+  available, so just pass it to createCall, the only exception is
+  CreateProbeReadStr which must have been refactored
+- getting the type of alloca instruction - there is a dedicated
+  AllocaInst::getAllocatedType method that can be used instead
+- strncmp - pass sizes of the strings to CreateStrncmp to be able to get
+  the correct string type (which is array of uint8)
