This may help us reproduce a failing build when all we have is a build
log, and will become much more important in batch mode when we
/really/ need to know what ended up in what batch.
For now, this doesn't include /output/ filelists, because David's
about to mess with that code anyway to make things better around
supplementary outputs in batch mode. There is one weirdness there,
though, which is that ArgsToFrontendInputsConverter peeks at the
outputs to see whether we're doing single-threaded or multi-threaded
WMO.
This means moving the output path into SupplementaryOutputPaths, and
using the same sort of diagnostic dispatching that serialized
diagnostics use. This is part of what's needed to run the migrator
in batch mode.
Tiny start-up time optimization noticed while looking at how we do
PrettyStackTraceProgram. Also add PrettyStackTraceProgram to a few
more of our testing tools, via the new PROGRAM_START macro.
This way we'll link against the key path component the other module provides instead of making fragile assumptions about its current implementation. Since external keypath lowering isn't fully implemented elsewhere in the compiler, this is enabled behind a staging flag.
external keypath staging
Before this patch, we have one flag (KeepSyntaxInfo) to turn on two syntax
functionalities of parser: (1) collecting parsed tokens for coloring and
(2) building syntax trees. Since sourcekitd is the only consumer of either of these
functionalities, sourcekitd by default always enables such flag.
However, empirical results show (2) is both heavier and less-frequently
needed than (1). Therefore, separating the flag to two flags makes more
sense, where CollectParsedToken controls (1) and BuildSyntaxTree
controls (2).
CollectingParsedToken is always enabled by sourcekitd because
formatting and syntax-coloring need it; however BuildSyntaxTree should
be explicitly switched on by sourcekitd clients.

The current implementation isn't really useful in the face of generic
overloads. It has never been enabled by default, and isn't useful to
keep around if it is disabled. If we ever want to bring it back,
we know where to look!
This check doesn't make sense anymore because we are still making changes to the old remangler, but not to the old demangler.
Also, this check didn't work in most cases anyway.

This new format more efficiently represents existing information, while
more accurately encoding important information about nested generic
contexts with same-type and layout constraints that need to be evaluated
at runtime. It's also designed with an eye to forward- and
backward-compatible expansion for ABI stability with future Swift
versions.
