Split -fsanitize=bounds to -fsanitize=array-bounds (for the frontend-inserted
check using the ubsan runtime) and -fsanitize=local-bounds (for the middle-end
check which inserts traps).
Remove -fsanitize=local-bounds from -fsanitize=undefined. It does not produce
useful diagnostics and has false positives (PR17635), and is not a good
compromise position between UBSan's checks and ASan's checks.
Map -fbounds-checking to -fsanitize=local-bounds to restore Clang's historical
behavior for that flag.
