Make the update_llc_test_checks script test independant of llc behavior
by using cat with static files to simulate llc output.

This allows changing llc without breaking the script test case.

The update script is executed in a temporary directory, so the
llc-generated assembly files are copied there. %T is deprecated, but it
allows copying a file with a predictable filename.

Import of Attr objects was incomplete in ASTImporter.
This change introduces support for a generic way of importing an attribute.
For an usage example import of the attribute AssertCapability is
added to ASTImporter.
Updating the old attribute import code and adding new attributes or extending
the generic functions (if needed) is future work.

When compiling the runtime with a version of clang-cl newer than 12, we
define CMPLXF as __builtin_complex, which returns a float _Complex type.
This errors out in contexts where the result of CMPLXF is expected to be
a float_Complex_t. This is defined as _Fcomplex whenever _MSC_VER is
defined (and as float _Complex otherwise).

This patch defines float_Complex_t & friends as _Fcomplex only when
we're using "true" MSVC, and not just clang-pretending-to-be-MSVC. This
should only affect clang-cl >= 12.

Two tests in span.cons/deduct.pass.cpp accidentally check whether the

These routines were add years ago during initial porting attempts to AIX and are mostly build hacks for routines which we're missing at the time, but are available now on recent AIX OS levels.

Thus builds on modern AIX OS levels no longer need these and they cause problems if you try to build the library with a generic triple (i.e. powerpc-ibm-aix) as we'll pull them in and encounter duplicate definitions from the OS.

a scope metadata node in case only one scope was in use in alias.scopes
or noalias metadata. It should always be a list of scopes. The verifier
change in 8700f2bd enforced this and
broke the test. Fix the translation to always create a list of scopes
using a new metadata node, update and reenable the respective test.
