For macOS >= 11 the fixit for narrowing an availability check rather
than adding a new one should fire if the major version is the same, like
on other platforms.
This does several different things to improve how platforms are described in availability diagnostics:
• Mentions the platform in diagnostics for platform-specific @available(unavailable) attributes.
• Replaces “OS X” with “macOS”.
• Replaces “fooOS application extension” with “application extensions for fooOS”.
• Replaces “on fooOS” with “in fooOS”.
Fixes <rdar://problem/49963341>.
Change the fix-it suggesting adding #available to be consistent with the fix-it
adding @available.
This changes "guard with version check" to "add if #available version check".

As Jordan notes, this uses the wrong check: isScriptMode() is also true for
main.swift in an app or command-line tool.
This reverts commit 8a72f4357bc04a386cf82acd1de06896515ab5a8.

We normally report a warning when a #available() check will always be true
because of the minimum deployment target. These warnings are potentially
annoying when the developer either cannot change the minimum deployment target
from the default (as in playgrounds) or when doing so is burdensome (as for
command-line scripts, which would require passing a target triple) -- so
suppress them.

This came out of today's language review meeting.
The intent is to match #available with the attribute
that describes availability.
This is a divergence from Objective-C.

Enable checking for uses of potentially unavailable APIs. There is
a frontend option to disable it: -disable-availability-checking.
This commit updates the SDK overlays with @availability() annotations for the
declarations where the overlay refers to potentially unavailable APIs. It also changes
several tests that refer to potentially unavailable APIs to use either #available()
or @availability annotations.

In source files that are in script mode, global variable initialization
expressions are eagerly executed. For this reason, disallow @availability
attributes having 'introduced=' on script-mode globals.
I had to rejigger a fair number of potential unavailability tests because they
weren't written with this distinction in mind.

Minor tweaks to availability diagnostic text based on feedback from Chris, Ted, and Doug.
This changees "'foo' is only available on OS X version 10.10 or greater" to
"'foo' is only available on OS X 10.10 or newer".
This change also updates the deprecation and obsoleted diagnostics to be consistent with
the new text.

We now suggest up to three Fix-Its for each reference to a potentially
unavailable symbol: one to wrap the reference in an if #os(...) { ... }
guard (if possible), one to add an @availability attribute to an enclosing
property or method (if possible), and one to add an @availability attribute
to an enclosing class/struct/extension, etc. or global function.
The goal here is not to infer the "best" Fix-It but rather to ensure
discoverability of #os() and @availability attributes. We want the user, when
faced with an availability diagnostic, to be aware of the tools in her toolbox
to deal with it.
This is still missing QoI improvements, including Fix-Its to update
existing @availability attributes and more precise wording in diagnostics
(e.g, "initializer" instead of function, "class" instead of "type"). These
improvements will come in later commits.

Resolving signatures of declarations from files other than the primary source
file causes first-pass type checking, including diagnostics for potential
unavailability, to be performed on those declarations. Prior to this commit, the
type refinement context hierarchy was only constructed for the primary file, so
spurious errors were emitted when checking declarations in other files. With
this commit, the availability checker builds the hierarchy for a source file the
first time its hierarchy is queried. We will eventually want to build the
hierarchy more lazily, but that will come later.
