Subject: parse: add support for no_sanitize_* attributes
Patch-mainline: no, submitted

gcc added support for new no_sanitize_* function attributes:
* no_address_safety_analysis
* no_sanitize_address
* no_sanitize_thread
* no_sanitize_undefined

The kernel uses at least no_sanitize_address as of now. So add them
(and their __...__ counterparts) to ignored_attributes as we can
safely ignore them.
