Subject: Ensure Ident_GNU_final is properly initialized in the Parser Initialize function
X-Git-Tag: llvmorg-4.0.0-rc1~13784

Ensure Ident_GNU_final is properly initialized in the Parser Initialize function

The recent change implementing __final forgot to initialize a variable.
This was caught by the Memory Sanitizer.

Properly initialize the value to nullptr to ensure proper memory reads.

Patch by Erich Keane!
