The double dash form is documented by GNU as, used by gcc, and accepted by llvm-mc.

Restore the `-gz` option to the driver with some minor tweaks to handle
the additional case for `-Wa,--compress-debug-sections`.
This intends to make the compression of the debug information
controllable from the driver. The following is the behaviour:
-gz enable compression (ambiguous for format, will default to zlib-gnu)
-gz=none disable compression
-gz=zlib-gnu enable compression (deprecated GNU style zlib compression)
-gz=zlib enable compression (zlib based compression)
Although -Wa,-compress-debug-sections works, it should be discouraged
when using the driver to invoke the assembler. However, we permit the
assembler to accept the GNU as style argument --compress-debug-sections
to maintain compatibility.
Note, -gz/-gz= does *NOT* imply -g. That is, you need to additionally
specific -g for debug information to be generated.

cc1as does not currently access the "--" version of this flag. At the
very least this needs to be fixed and proper test cases need to be
added.
Simple reproducer:
clang -Wa,--compress-debug-sections /tmp/test.cc
Result:
error: unknown argument: '--compress-debug-sections'

Split the no-ias tests and give them a target to ensure that they go
down the GNU toolchain path. Adjust the no compression support tests.

These options control the behaviour of the compression of debug info
sections on ELF targets. Our behaviour slightly diverges from the
behaviour of GCC. `-gz` maps to the `-compress-debug-sections` rather
than `-compress-debug-sections=zlib` or
`-compress-debug-sections=zlib-gnu`. This small divergence allows us to
be compatible across versions of binutils (=zlib support was introduced
in 2.26, while earlier versions only support =zlib-gnu). This also
allows users to not have to worry about the version of the assembler
they may be using if they are not using the IAS. Previously, users
would have had to go through the internal option
`-compress-debug-sectionss` and pass that through to the assembler,
which is no longer needed.

Rather than validating the flags, pass them through without any
validation. Arguments passed via -Wa or -Xassembler are passed directly
to the assembler without validation. The validation was previously
required since we did not provide proper driver level support for
controlling the debug compression on ELF targets. A subsequent change
will add support for the `-gz` and `-gz=` flags which provide proper
driver level control of the ELF compressed debug sections.

Fallout from r205261, ensure it doesn't matter how we disable compressed
debug info, even if zlib is missing and that we warn when we don't have
zlib and don't warn when we do, all while silently suppressing these
tests on the systems they weren't intended for...

Another shot in the dark, since I do have zlib installed. Will be
watching the bots for fallout.
