[PATCH] Add experimental clang/driver flag -fsanitize-address-field-padding=N

[Kostya Serebryany]

Hi samsonov,

This change adds an experimental flag -fsanitize-address-field-padding=N (0, 1, 2)
to clang and driver. With this flag ASAN will be able to detect some cases of
intra-object-overflow bugs,
see https://code.google.com/p/address-sanitizer/wiki/IntraObjectOverflow

There is no actual functionality here yet, just the flag parsing.
The functionality will be sent for review separately.
