  Log Message:
  -----------
  [ValueTracking] Allow context-sensitive nullness check for non-pointers

Same as D60846 but with a fix for the problem encountered there which
was a missing context adjustment in the handling of PHI nodes.

The test that caused D60846 to be reverted was added in e15ab8f277c7.
