[XRay][clang+compiler-rt] Support build-time mode selection

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 makes us hit an assert where we can't reach the emergency spill

6 years ago[X86][Broadwell] HWPort5 should not be added to BroadwellModelProcResources.
Andrea Di Biagio [Tue, 10 Apr 2018 10:49:41 +0000 (10:49 +0000)]
[X86][Broadwell] HWPort5 should not be added to BroadwellModelProcResources.

The BroadwellModelProcResources had an entry for HWPort5, which is a Haswell
resource, and not a Broadwell processor resource. That entry was added to the
Broadwell model because variable blends were consuming it.

This was clearly a typo (the resource name should have been BWPort5), which
unfortunately was never caught before. It was not reported as an error because
HWPort5 is a resource defined by the Haswell model. It has been found when
testing some code with llvm-mca: the list of resources in the resource pressure
view was odd.

This patch fixes the issue; now variable blend instructions consume 2 cycles on
BWPort5 instead of HWPort5. This is enough to get rid of the extra (spurious)
entry in the BroadWellModelProcResources table.

Args: replace isprint8 usage with isprint

It looks like we introduced isprint8 way back in r169417 to be used on
getopt's short_options, which we sometimes set to values which are out
of range for normal chars to indicate options with no short form.

However, this is not how the function is used in the Args class, where
we explicitly process a string character by character.

This removes the last external dependency from the Args class.

classes into a separate class. This way, the Args class can be turned
into a lightweight arc+argv wrapper and moved into the lower lldb
