[PATCH] D36562: [Bitfield] Make the bitfield a separate location if it has width of legal integer type and its bit offset is naturally aligned for the type

[Wei Mi via Phabricator via llvm-commits]

wmi added a comment.

Changes following the discussion:

- Put the bitfield split logic under an option and off by default.
- When sanitizer is enabled, the option for bitfield split will be ignored and a warning message will be emitted.

In addition, a test is added.
