Emit error for use of 128-bit integer inside device code had been
already implemented in https://reviews.llvm.org/D74387. However,
the error is not emitted for SPIR64, because for SPIR64, hasInt128Type
return true.
hasInt128Type: is also used to control generation of certain 128-bit
predefined macros, initializer predefined 128-bit integer types and
build 128-bit ArithmeticTypes. Except predefined macros, only the
device target is considered, since error only emit when 128-bit
integer is used inside device code, the host target (auxtarget) also
needs to be considered.
The change address:
1. (SPIR.h) Correct hasInt128Type() for SPIR targets.
2. Sema.cpp and SemaOverload.cpp: Add additional check to consider host
target(auxtarget) when call to hasInt128Type. So that __int128_t
and __int128() are allowed to avoid error when they used outside
device code.
3. SemaType.cpp: add check for SYCLIsDevice to delay the error message.
The error will be emitted if the use of 128-bit integer in the device

This reverts commit 3b18a594c7, since
apparently this doesn't work everywhere. E.g.,

Push `FileEntryRef` and `DirectoryEntryRef` further, using it them

- Fix the `DirectoryEntryRef` constructor from `MapEntry` to take it by

Android has a handful of API levels relevant to developers described
here: https://developer.android.com/studio/build#module-level.
`__ANDROID_API__` is too vague and confuses a lot of people. Introduce
a new macro name that is explicit about which one it represents. Keep
the old name around because code has been using it for a decade.
Add `FileEntryRef::getDir`, which returns a `DirectoryEntryRef`. This
includes a few changes:
- Customize `OptionalStorage` so that `Optional<DirectoryEntryRef>` is
pointer-sized (like the change made to `Optional<FileEntryRef>`).
Factored out a common class, `FileMgr::MapEntryOptionalStorage`, to
reduce the code duplication.
- Store an `Optional<DirectoryEntryRef>` in `FileEntryRef::MapValue`.
This is set if and only if `MapValue` has a real `FileEntry`.
- Change `FileManager::getFileRef` and `getVirtualFileRef` to use
`getDirectoryRef` and store it in the `StringMap` for `FileEntryRef`.

Shrink `FileEntryRef` to the size of a pointer, by having it directly
reference the `StringMapEntry` the same way that `DirectoryEntryRef`
does. This makes `FileEntryRef::FileEntryRef` private as a side effect
(`FileManager` is a friend!).
There are two helper types added within `FileEntryRef`:
- `FileEntryRef::MapValue` is the type stored in
`FileManager::SeenFileEntries`. It's a replacement for
`SeenFileEntryOrRedirect`, where the second pointer type has been
changed from `StringRef*` to `MapEntry*` (see next bullet).
- `FileEntryRef::MapEntry` is the instantiation of `StringMapEntry<>`
where `MapValue` is stored. This is what `FileEntryRef` has a pointer
to, in order to grab the name in addition to the value.
