As outlined in a previous RFC, the test/ASTMerge/Inputs folder is getting full and the tests are starting to become interdependent. This is undesirable because
- it makes it harder to write new tests
- it makes it harder to figure out at a glance what old tests are doing, and
- it adds the risk of breaking one test while changing a different one, because of the interdependencies.
To fix this, according to the conversation in the RFC, I have changed the layout from
a.c
Inputs/a1.c
Inputs/a2.c
to
a/test.c
a/Inputs/a1.c
a/Inputs/a2.c
for all existing tests. I have also eliminated interdependencies by replicating the input files for each test that uses them.

These test updates almost exclusively around the change in behavior
around enum: enums without a definition are considered incomplete except
when targeting MSVC ABIs. Since these tests are interested in the
'incomplete-enum' behavior, restrict them to %itanium_abi_triple.

some bugs in the ASTImporter that this exposed:
- When importing functions, the body (if any) was
previously ignored. This patch ensures that the
body is imported also.
- When a function-local Decl is imported, the first
thing the ASTImporter does is import its context
(via ImportDeclParts()). This can trigger
importing the Decl again as part of the body of
the function (but only once, since the function's
Decl has been added to ImportedDecls). This patch
fixes that problem by extending ImportDeclParts()
to return the imported Decl if it was imported as
part of importing its context, and the patch adds
ASTImporter::GetAlreadyImportedOrNull() to support
this query. All callers of ImportDeclParts return
the imported version of the Decl if ImportDeclParts()
returns it.
- When creating functions, InnerLocStart of the source
function was re-used without importing. This is a
straight up bug, and this patch makes ASTImporter
import the InnerLocStart and use the imported version.
- When importing FileIDs, the ASTImporter previously
always tried to re-load the file for the corresponding
CacheEntry from disk. This doesn't work if the
CacheEntry corresponds to a named memory buffer. This
patch changes the code so that if the UniqueID for the
cache entry is invalid (i.e., it is not a disk file)
the whole entry is treated as if it were invalid, which
forces an in-memory copy of the buffer.
Also added test cases, using the new support committed in
236011.
