blocks and lambdas
Prior to this commit Clang emitted the old "partial availability" warning for
expressions that referred to declarations that were not yet introduced in
blocks and lambdas that were not in a function/method. This commit ensures that
top-level blocks and lambdas use the new unguarded availability checks.

This is done so that the following compiles with no warnings:
int fn(type_10_12) __attribute__((availability(macos, introduced=10.12)));

This commit adds a traversal of the AST after Sema of a function that diagnoses
unguarded references to declarations that are partially available (based on
availability attributes). This traversal is only done when we would otherwise
emit -Wpartial-availability.
This commit is part of a feature I proposed here:
