triple in addition to -darwin
The previous check incorrectly checked for macOS support by
allowing -darwin triples only, and -macos triple was not supported.

The test 'test/Driver/XRay/xray-instrument-os.c' is supposed to XFAIL on -darwin triples.
However, LLVM can be configured to be built with a -macos triple instead, which is equivalent
to -darwin. This commit updates the XFAIL condition to also XFAIL with a -macos host triple.

Summary:
Add a test and ensure that we propagate the
-fxray-instrumentation-bundle flag from the driver invocation to the
-cc1 options.

This confirms expectations for multiple values provided through the
driver when selecting specific modes and the order of appearance of
individual values for the `-fxray-modes=` flag.
This change just adds more test cases to an existing test file.
llvm-svn: 339662
Summary:
This allows us to do the following:
clang -fxray-modes=none ... -fxray-modes=xray-basic
It's important to be able to do this in cases where we'd like to
specialise the configuration for the invocation of the compiler, in
various scripting environments.
This is related to llvm.org/PR37066, a follow-up to D45474.

llvm-svn: 329989
Summary:
This patch implements the `-fxray-modes=` flag which allows users
building with XRay instrumentation to decide which modes to pre-package
into the binary being linked. The default is the status quo, which will
link all the available modes.
For this to work we're also breaking apart the mode implementations
(xray-fdr and xray-basic) from the main xray runtime. This gives more
granular control of which modes are pre-packaged, and picked from
clang's invocation.
This fixes llvm.org/PR37066.
Note that in the future, we may change the default for clang to only
contain the profiling implementation under development in D44620, when
that implementation is ready.

This is a follow-up to D45354, which we should have only been running on
Linux and FreeBSD for specific targets.
Differential Revision: https://reviews.llvm.org/D45354
llvm-svn: 329378
Summary:
This change introduces `-fxray-link-deps` and `-fnoxray-link-deps`. The
`-fnoxray-link-deps` allows for directly controlling which specific XRay
runtime to link. The default is for clang to link the XRay runtime that
is shipped with the compiler (if there are any), but users may want to
explicitly add the XRay dependencies from other locations or other
means.

Summary:
This change ensures that we don't link in the XRay runtime when building
shared libraries with clang. This doesn't prevent us from building
shared libraris tht have XRay instrumentation sleds, but it does prevent
us from linking in the static XRay runtime into a shared library.
The XRay runtime currently doesn't support dynamic registration of
instrumentation sleds in shared objects, which we'll start enabling in
the future. That work has to happen in the back-end and in the runtime.
