[PATCH] analyzer: Define INCLUDE_UNIQUE_PTR

[PATCH] analyzer: Define INCLUDE_UNIQUE_PTR

[Maxim Blinov]

Un-break the build for AArch64 Darwin. Build currently fails with an
error very similar to pr82091:

```
In file included from ../../../gcc-master-wip-apple-si/gcc/analyzer/engine.cc:69:
In file included from /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/v1/memory:678:

    _VSTD::abort();
    ^~~~~~~

extern void fancy_abort (const char *, int, const char *)
            ^
```

Judging from the following comment in gcc/system.h, we just need to
define INCLUDE_UNIQUE_PTR since commit eafa9d96923 added the inclusion
of <memory>:

```
/* Some of the headers included by <memory> can use "abort" within a
   namespace, e.g. "_VSTD::abort();", which fails after we use the
   preprocessor to redefine "abort" as "fancy_abort" below.
   Given that unique-ptr.h can use "free", we need to do this after "free"
   is declared but before "abort" is overridden.  */

```

Sorry about the breakage.

Does the patch fix the build for you?

If so, looks good for trunk.  Please reference PR bootstrap/102242 in
the ChangeLog entry.

Thanks
