Steven Wu 3bb4aa566e [Availability] Improve availability to consider functions run at load time
Summary:
There are some functions/methods that run when the application launches
or the library loads. Those functions will run reguardless the OS
version as long as it satifies the minimum deployment target. Annotate
them with availability attributes doesn't really make sense because they
are essentially available on all targets since minimum deployment
target.

Erik Pilkington ba87c626f9 [Sema] Don't emit -Wunguarded-availability for switch cases
This made it awkward to switch over an enum where some entries
are partial and is unlikley to catch any bugs.

Alex Lorenz cdd596fcde [ObjC] Avoid the -Wunguarded-availability warnings for protocol
requirements in protocol/class/category declarations

The unguarded availability warnings in the protocol requirements of a protocol
/class/category declaration can be avoided. This matches the behaviour of
Swift's diagnostics. The warnings for deprecated/unavailable protocols are
preserved.

Alex Lorenz 28559ceece -Wunguarded-availability should support if (@available) checks in top-level
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.

Erik Pilkington 5cd57177a5 [ObjC] Warn on unguarded use of partial declaration
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:
