Adds a new flag "-experimental-skip-all-function-bodies" that skips
typechecking and SIL generation for all function bodies (where
possible).
`didSet` functions are still typechecked and have SIL generated as their
body is checked for the `oldValue` parameter, but are not serialized.
Parsing will generally be skipped as well, but this isn't necessarily
the case since other flags (eg. "-verify-syntax-tree") may force delayed
parsing off.
The new message is:
"Please submit a bug report (https://swift.org/contributing/#reporting-bugs) and include the crash backtrace."
1. In crash logs we used to print a message which points to the llvm bug tracking page. Now it points to the swift.org bug tracking guidelines.
2. Use the same message in all compiler diagnostics which ask the user to file a bug report.

The original remark message “could not acquire lock file for module interface” sounds too severe.
It may confuse users that this is a serious issue. We should rephrase it to a less obtrusive one.

Prebuilt-module directory now contains a SystemVersion.plist file copied from the SDK
it's built from. This patch teaches the compiler to remark this version and the SDK version
when -Rmodule-interface-rebuild is specified. The difference between these versions could
help us debug unusable prebuilt modules.
This scanning mode allows swift-driver to query module dependencies in a batch
and in a more granular way. In short term, it could help solve a problem that
clang module dependencies may vary if target triple changes. In a longer term,
we could break a holistic dependencies graph into smaller pieces for better caching
and reusing.
This change doesn't include the implementation of using the specified scanner
arguments to set up Clang dependencies scanner. It will come in later commits.
Instead of taking paths of Swift module files from front-end command line
arguments, we should take a JSON file specifying details of explicit modules.
The advantages is (1) .swiftdoc and .swiftsourceinfo can be associated
with a .swiftmodule file, and (2) module names are explicitly used as
keys in the JSON input so we don't need to eagerly deserialize a .swiftmodule
file to collect the module name.
Previously the path to covered files in the __LLVM_COV / __llvm_covmap
section were absolute. This made remote builds with coverage information
difficult because all machines would have to have the same build root.
This change uses the values for `-coverage-prefix-map` to remap files in
the coverage info to relative paths. These paths work correctly with
llvm-cov when it is run from the same source directory as the
compilation, or from a different directory using the `-path-equivalence`
argument.
This is analogous to this change in clang https://reviews.llvm.org/D81122
To support -disable-implicit-swift-modules, the explicitly built modules
are passed down as compiler arguments. We need this new module loader to
handle these modules.
This patch also stops ModuleInterfaceLoader from building module from interface
when -disable-implicit-swift-modules is set.
Now that we no longer perform whole-file type
checking for code completion, the ASTVerifier is
no longer expecting fully semantically valid AST.
As such, we no longer need to emit an error to
force it to be more lax with its checks.
Add ModuleImplicitImportsRequest, which computes
the modules that should be implicitly imported by
each file of a given module. Use this request in
import resolution to add all the necessary
implicit imports.
The request computes the implicit imports by
consulting the ImplicitImportInfo, which ModuleDecl
can now be created with. This allows us to remove
uses of `SourceFile::addImports` in favor of
adding modules needed to be implicitly imported to
the ImplicitImportInfo.
Some code paths that see target triples go through the frontend
without seeing the driver. Therefore, perform the same "simulator"
inference for x86 iOS/tvOS/watchOS triples also in the frontend,
to ensure that we remain compatible. Also make sure that
-print-target-info performs the appropriate adjustment.

These were duplicated in 11 different files, and as they've gotten more
complex a few inconsistencies have snuck in. Sharing them should make future
changes easier and less bug-prone.
This went unnoticed because the tests for failure were pulled out due to
non-deterministic behavior.
The correct ordering of arguments is non-cascading first because the bit
this is reading is phrased as "is this edge cascading" not "is this edge
private"
This allows the usage of the whole remark infrastructure developed in
LLVM, which includes a new binary format, metadata in object files, etc.
This gets rid of the YAMLTraits-based remark serialization and does the
plumbing for hooking to LLVM's main remark streamer.
For more about the idea behind LLVM's main remark streamer, see the
docs/Remarks.rst changes in https://reviews.llvm.org/D73676.
The flags are now:
* -save-optimization-record: enable remarks, defaults to YAML
* -save-optimization-record=<format>: enable remarks, use <format> for
serialization
* -save-optimization-record-passes <regex>: only serialize passes that
match <regex>.
The YAMLTraits in swift had a different `flow` setting for the debug
location, resulting in some test changes.
Static-linked libraries could add symbols to the final tbd file. We need
this flag to specify additional module names to collect symbols from.
rdar://59399684
Using the new linker directives $ld$previous requires the compiler to know the previous
install names for the symbols marked as removed. This patch teaches the compiler
to take a path to a Json file specifying the map between module names and previous
install names. Also, these install names can be platform-specific.

This ensures only one process is generating module cache from an interface
file so that we don't blow up memory usage when multiple processes are
doing the same. The locking mechanism is similar to that of Clang's.
A better approach is that the build system takes care of the module building
step as a formal dependency.

Frontend outputs source-as-compiled, and source-ranges file with function body ranges and ranges that were unparsed in secondaries.
Driver computes diffs for each source file. If diffs are in function bodies, only recompiles that one file. Else if diffs are in what another file did not parse, then the other file need not be rebuilt.
