Move expected-fail cases from directive-cpu.s to
directive-cpu-err.s. This allows us to remove the 'not' from the
llvm-mc invocation in directive-cpu.s so that this test will fail
in unexpected error cases. It also means that we are not relying
on all stderr coming before any stdout, which seems fragile.
Also make use of CHECK-NEXT to ensure that multiline error messages
really are occuring together.
And add a test to verify that .cpu with an arch version as extension
is rejected.

That's only a required extension as of v8.1a.
Remove it from the "generic" CPU as well: it should only support the
base ISA (and binutils agrees).
Also unify the MC tests into crc.s and arm64-crc32.s

r288279 mistakenly added it to all arches, but it's only available
from v8.1 onwards.
The testcase is awkward, because (I suspect) of PR32873.
Spotted by inspection.

Summary:
This is preparation for ThunderX processors that have Large
System Extension (LSE) atomic instructions, but not the
other instructions introduced by V8.1a.
This will mimic changes to GCC as described here:
https://gcc.gnu.org/ml/gcc-patches/2015-06/msg00388.html
LSE instructions are: LD/ST<op>, CAS*, SWP

Fix the .arch asm parser to use the full set of features for the architecture
and any extensions on the command line. Add and update testcases accordingly
as well as add an extension that was used but not supported.
