This patch adds support for serialization and deserialization of
debug scopes.
Debug scopes are serialized in post order and enablement is
controlled through the experimental-serialize-debug-info flag which
is turned off by default. Functions only referred to by these debug
scopes are deserialized as zombie functions directly.
Add flag `-load-resolved-plugin` to load macro plugin, which provides a
pre-resolved entry into PluginLoader so the plugins can be loaded based
on module name without searching the file system. The option is mainly
intended to be used by explicitly module build and the flag is supplied
by dependency scanner.
Today ParenType is used:
1. As the type of ParenExpr
2. As the payload type of an unlabeled single
associated value enum case (and the type of
ParenPattern).
3. As the type for an `(X)` TypeRepr
For 1, this leads to some odd behavior, e.g the
type of `(5.0 * 5).squareRoot()` is `(Double)`. For
2, we should be checking the arity of the enum case
constructor parameters and the presence of
ParenPattern respectively. Eventually we ought to
consider replacing Paren/TuplePattern with a
PatternList node, similar to ArgumentList.
3 is one case where it could be argued that there's
some utility in preserving the sugar of the type
that the user wrote. However it's really not clear
to me that this is particularly desirable since a
bunch of diagnostic logic is already stripping
ParenTypes. In cases where we care about how the
type was written in source, we really ought to be
consulting the TypeRepr.
It might be unexpected to future users that `-swift-compiler-version`
would produce a version aligned to .swiftinterface instead of one used
to build the .swiftmodule file. To avoid this possible confusion, let's
scope down the version to `-interface-compiler-version` flag and
`SWIFT_INTERFACE_COMPILER_VERSION` option in the module.
If swiftinterface doesn't have `-swift-compiler-version` flag
it means that it was generated with an older version of the
Swift compiler. In such cases it would be incorrect to use
"current" compiler version because the field is intended to
indicate the compiler the swiftinterface was built with.
`Builtin.FixedArray<let N: Int, T: ~Copyable & ~Escapable>` has the layout of `N` elements of type `T` laid out
sequentially in memory (with the tail padding of every element occupied by the array). This provides a primitive
on which the standard library `Vector` type can be built.
The thunk's parameter needs the @in_guaranteed convention if it's a
const reference parameter. However, that convention wasn't being used
because clang importer was removing the const reference from the
type and SILGen was computing the type of the parameter based on the
type without const reference.
This commit fixes the bug by passing the clang function type to
SILDeclRef so that it can be used to compute the correct thunk type.
This fixes a crash when a closure is passed to a C function taking a
pointer to a function that has a const reference struct parameter.
This recommits e074426 with fixes to
serialization/deserialization of function types. The fixes prevent clang
types of functions from being dropped during serialization.

In an explicit build LLDB needs to be able import the unmodified .pcms, so
having the exact same flags matters there, and there is no risk of a
recompilation failure, because nothing is recompiled.

Add function to handle all macro dependencies kinds in the scanner,
including taking care of the macro definitions in the module interface
for its client to use. The change involves:
* Encode the macro definition inside the binary module
* Resolve macro modules in the dependencies scanners, including those
declared inside the dependency modules.
* Propagate the macro defined from the direct dependencies to track
all the potentially available modules inside a module compilation.
OptionBlocks has missing block record for some of the record types. Add
the missing record types into block info block and order the block
record in the same order as the declaration so it is easier to check for
which kind is missing.
