Remove the thread name caching code. It does not handle the possibility
of thread name changing between requests, therefore breaking

Fix TestGdbRemoteThreadName to call ::pthread_setname_np instead
of ::pthread_set_name_np on FreeBSD. While technically both names
are correct, the former is preferable because of compatibility
with Linux. Furthermore, the latter requires `#include <pthread_np.h>`
that was missing causing the test to fail to compile.

The debug location is removed from any outlined instruction. This
causes the MachineVerifier to crash on outlined DBG_VALUE
instructions.
Then, debug instructions are "invisible" to the outliner, that is, two
ranges of instructions from different functions are considered
identical if the only difference is debug instructions. Since a debug
instruction from one function is unlikely to provide sensible debug
information about all functions, sharing an outlined sequence, this
patch just removes debug instructions from the outlined functions.

These options are in practice passes to the external tool (defined with
F18_FC), i.e. fall into "unrecognised" category. No need to keep them
among other options that are actually parsed.
The _F and _D registers are already sub/super registers. When one gets allocated all its aliases are already marked as allocated. We don't need to explicitly shadow it too.
I believe shadow is for calling conventions like 64-bit Windows on X86 where have rules like this
CCIfType<[i32], CCAssignToRegWithShadow<[ECX , EDX , R8D , R9D ],
[XMM0, XMM1, XMM2, XMM3]>>
For that calling convention the argument number determines which register is used regardless of how many scalars or vectors came before it.

Currently, vendor-specific availability markup is enabled by default.
This means that even when building against trunk libc++, the headers
will by default prevent you from using some features that were not
released in the dylib on your target platform. This is a source of
frustration since people building libc++ from sources are usually not
trying to use some vendor's released dylib.
For that reason, I've been thinking for a long time that availability
annotations should be off by default, which is the primary change that
this commit enables.
In addition, it reworks the implementation to make it easier for new
vendors to add availability annotations for their platform, and it
refreshes the documentation to reflect the current state of the codebase.
Finally, a CMake configuration option is added to control whether
availability annotations should be turned on for the flavor of libc++
being created. The intent is for vendors like Apple to turn it on, and
for the upstream libc++ to leave it off (the default).

5d64574301 removes this enum value and now
all the switch statements that previously relied on handling this in the
'default' branch are causes compiler warnings due to redundant default cases.
This just removes the now unreachable code in there.
In D89056 the default value for architecture was moved to `build` so that
all called functions see the same architecture value. It seems there are a
few functions that call buildDefault directly (and not via build), so
on some test configurations that set a custom arch value the architecture
value is no longer available.
This just adds the architecture code from build to buildDefault to get
the bots green again while I'm looking for a better solution.
As described here:

In order to allow Lambdas to be used with traditional Win32 APIs, they
emit a conversion function for (what Raymond Chen claims is all) a
number of the calling conventions. Through experimentation, we
discovered that the list isn't quite 'all'.
This patch implements this by taking the list of conversions that MSVC
emits (across 'all' architectures, I don't see any CCs on ARM), then
emits them if they are supported by the current target.
However, we also add 3 other options (which may be duplicates):
free-function, member-function, and operator() calling conventions. We
do this because we have an extension where we generate both free and
member for these cases so th at people specifying a calling convention
on the lambda will have the expected behavior when specifying one of
those two.
MSVC doesn't seem to permit specifying calling-convention on lambdas,
but we do, so we need to make sure those are emitted as well. We do this
so that clang-only conventions are supported if the user specifies them.

Clang offers a `-f[no]-show-column` flag for hiding the column numbers when
printing diagnostics but there is no option for doing the same with line
numbers.
In LLDB having this option would be useful, as LLDB sometimes only knows the
file name for a SourceLocation and just assigns it the dummy line/column `1:1`.
These fake line/column numbers are confusing to the user and LLDB should be able
to tell clang to hide *both* the column and the line number when rendering text
diagnostics.
This patch adds a flag for also hiding the line numbers. It's not exposed via
the command line flags as it's most likely not very useful for any user and can
lead to ambiguous output when the user decides to only hide either the line or
the column number (where `file:1: ...` could now refer to both line 1 or column
1 depending on the compiler flags). LLDB can just access the DiagnosticOptions
directly when constructing its internal Clang instance.
The effect doesn't apply to Vi/MSVC style diagnostics because it's not defined
how these diagnostic styles would show an omitted line number (MSVC doesn't have
such an option and Vi's line mode is theory only supporting line numbers if I
understand it correctly).

This originally broke the TestQuoting which explicitly called buildDefault
instead of calling build() and marking the test as no_debug_info_test.
TestQuoting has been rewritten by now and is using `build`, so this should now
pass on all platforms.
Original summary:
The Darwin builder currently assumes in `getArchCFlags` that the passed `arch`
value is an actual string it can string.join with vendor/os/version/env strings:
```
triple = '-'.join([arch, vendor, os, version, env])
```
However this is not true for most tests as we just pass down the `arch=None`
default value from `TestBase.build`. This causes that if we actually end up in
this function we just error out when concatenating `None` with the other actual
strings of vendor/os/version/env. What we should do instead is check that if
there is no test-specific architecture that we fall back to the configuration's
architecture value.
It seems we already worked around this in `builder.getArchSpec` by explicitly
falling back to the architecture specified in the configuration.
This patch just moves this fallback logic to the top `build` function so that it
affects all functions called from `TestBase.build`.
