Allow the preprocessor to cache the lexed tokens, so that we can do efficient lookahead and backtracking.
...
1) New public methods added:
-EnableBacktrackAtThisPos
-DisableBacktrack
-Backtrack
-isBacktrackEnabled
2) LookAhead() implementation is replaced with a more efficient one.
3) LookNext() is removed.

Fix Sema::MergeVarDecl() to better handle type compatibility. The previous code was trying to handle arrays specially (which didn't work for pointers to array). Removed local helper function areEquivalentArrayTypes(), replacing it's use with the more general ASTContext::typesAreCompatible() predicate.
...
Even though the test case this fixes is in "tentative-decls.c", this bug didn't have anything to do with our handling of tentative definitions (which is what I first expected). In any event, this is a tricky area of the spec.

Fix issues with C "tentative" definitions.

- Move checking from MergeVarDecl->FinializeDeclaratorGroup. Since MergeVarDecl is called before the initializer is attacted, it can't be done there (this removes a long standing FIXME).

- Remove FIXME's and touch-up test case.
Still some more work to do (forthcoming)...
