InitListChecker::CheckListElementTypes(): Check for function types and issue an appropriate diagnostic.

Cleanup from yesterday...make isTentativeDefinition() a static helper function (no need for it to be part of the Sema API).

Sema::CheckForFileScopedRedefinitions(): Make sure tentative decls of incomplete array types are completed (and diagnosed properly).

llvm-svn: 54612

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.

number of initializers that will be consumed, not the number of members 
to iterate through.  Fixes PR2534.

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.
