Currently, whenever GHC catches a segfault on Windows, it simply reports the somewhat uninformative message `Segmentation fault/access violation in generated code`. This patch adds to the message the type of violation (read/write/dep) and location information, which should help debugging segfaults in the future. Fixes #13108.
