This means it can be emitted during an -emit-module frontend job, which is the
most common place it will be used, so reusing work like this is important for
performance.
For now, this has to happen as part of a single frontend invocation, i.e. -wmo
or -force-single-frontend-invocation.
pass it to the PCH-generation job.
This depends on the merge-modules patch because we don't want merging
modules when optimization is enabled to re-run the optimizer.

Currently we have a number of unsolved disjunctions hard-coded to 5,
which breaks some existing code by terminating shrinking too early.
This patch makes it a command-line option so users have control over
what that threshold can be.
Resolves: rdar://problem/33433595
Typo correction can be particularly expensive, so introduce a
command-line flag to limit the number of typo corrections we will
perform per type-checker instance. Default this limit to 10.
Addresses rdar://problem/28469270 to some extent.
- Reordering the auto link files when linking in static libraries
and object files is required because the ordering of arguments
is important, and the dependant libraries need to come after the
objects/libs that require them. This is not a problem for
libswiftCore.a but can be an issue with libs that sit on top of
it, e.g. libFoundation.a
- Dont add an -rpath to the Swift dynamic libraries if using
-static-stdlib
This updates the rpath linking logic to only add the rpath that points
to the swift dylibs in the case that the libraries are not statically
linked into the binary.
With this patch different sanitizers (tsan/asan) will be enabled or
disabled on the driver level on a particular OS depending on whether
the required library is present.
The current patch only supports Darwin architectures, but Linux support
should not be hard to add.
Previously it was passing a relative filename and the invocation was creating .dia files in the source directory.
If a filename is not determined for inside the PCH output directory, it fallsback to creating a temporary for the diagnostics file,
similarly to the non-persistent bridging PCH job.

This helps disambiguate files that might otherwise be hard to sort through
if multiple runs output stats together in a single directory. The names
don't have to be perfect, just contain sufficient hints (and be parseable)
to differentiate module, arch, opt and output-type variation in jobs.
This should make it easier to rerun crashed jobs that use filelists;
previously you'd have to run the top-level driver command again with
-save-temps. I didn't want to save /all/ temporary files because that
often includes things like .o files, which could fill up your disk
pretty quickly. But we can always tweak this later.
