Introduce availability macros defined by a frontend flag. This feature makes it possible to set the availability versions at the moment of compilation instead of having it hard coded in the sources. It can be used by projects with a need to change the availability depending on the compilation context while using the same sources. The availability macro is defined with the `-define-availability` flag: swift MyLib.swift -define-availability "_iOS8Aligned:macOS 10.10, iOS 8.0" .. The macro can be used in code instead of a platform name and version: @available(_iOS8Aligned, *) public func foo() {} rdar://problem/65612624
Availability macros can’t be used in inlinable code as inlinable is copied textually in the generated swiftinterface files. Further would could lift this limitation.
…tion from a target without running the target. The routine already supports dumping the assembly to file if we are at a breakpoint using the current frame. This adds a -n option so one can without running just dump the assembly to a file of a specific function in a binary.

The driver will eventually use this to compute the input status of a merge-modules job.
Plumb the logic necessary to schedule merge-modules incrementally. This means that if any inputs jobs to merge-modules run, merge-modules is run. But, if they are all skipped, merge-modules will be skipped as well. This requires some light special-casing of the legacy driver's incremental job handling because it assumes in a few places it can always extract a swiftdeps file. This invariant will be further broken when the precompile step for bridging headers is skipped as well. rdar://65893400
Instead, let's rely on the existing source range assertions. They will fire if we add two nodes with overlapping or equal source ranges.

In order to unblock the SwiftWASM project, which relies on an incremental build of the Swift driver that relies on the merge-modules job always being run. The situation appears to be something like this: 1) An incremental build is run 2) Temporary swiftmodule outputs are laid down 3) merge-modules is skipped 4) modulewrap is run anyways and reads the empty temp file We should fix this by skipping modulewrap if we can skip merge-modules. But for now, be conservative and fall back to the status quo behavior of always running merge-modules whenever we encounter a modulewrap job.
