compiler-context-analysis: Add test stub

Browse Source 
Add a simple test stub where we will add common supported patterns that
should not generate false positives for each new supported context lock.

This builds the test for compiler-based context analysis. The test
does not add executable code to the kernel, but is meant to test that
common patterns supported by the analysis do not result in false
positive warnings.
When adding support for new context locks, it is strongly recommended
to add supported patterns to this test.
