Move Args.cpp from Interpreter to Utility

Summary:
The Args class is used in plenty of places besides the command
interpreter (e.g., anything requiring an argc+argv combo, such as when
launching a process), so it needs to be in a lower layer. Now that the
class has no external dependencies, it can be moved down to the Utility
module.

This removes the last (direct) dependency from the Host module to
Interpreter, so I remove the Interpreter module from Host's dependency
list.

Without these comments, by "luck" the contents of SomeKit's SKWidget.h

havoc if anything canonicalizes on the inode and your filesystem assigns
a common inode to files with identical file content. Alternatively, if
your build system uses symlinks into a content-addressed-storage (as
Google's does), you end up with these files being symlinks to the same
file.

The end result is that Clang deduplicates them internally, and then
believes that the SomeKit framework includes the SomeKitCore.h header,
and does not include the SKWidget.h in SomeKit. This in turn results in
warnings in this test and eventually errors as Clang becomes confused

Defer adding keywords to the identifier table until after the language options have been loaded from the AST file.

This fixes issues with "class" being reported as an identifier in "enum class" because the construct is not present when using default language options.

build: reserve `--color-diagnostics` for lld

When building out-of-tree compilers (e.g. swift), the linker check here
may yield incorrect values.  Ensure that we are using lld before we
attempt to use `--color-diagnostics` for the linker.  Other linkers (i.e
bfd, gold) do not support this flag and the test can pass in some cases
and then fail subsequently when building.

[ORC] Add a MaterializationResponsibility class to track responsibility for
materializing function definitions.

MaterializationUnit instances are responsible for resolving and finalizing
symbol definitions when their materialize method is called. By contract, the
MaterializationUnit must materialize all definitions it is responsible for and
no others. If it can not materialize all definitions (because of some error)
then it must notify the associated VSO about each definition that could not be
materialized. The MaterializationResponsibility class tracks this
responsibility, asserting that all required symbols are resolved and finalized,
and that no extraneous symbols are resolved or finalized. In the event of an
error it provides a convenience method for notifying the VSO about each
definition that could not be materialized.
