testsuite: i386: Skip gcc.target/i386/avx512cd-vpbroadcastmb2q-2.c etc. with Solaris as [PR114150]

Two avx512cd tests FAIL to assemble with the Solaris/x86 assembler:

FAIL: gcc.target/i386/avx512cd-vpbroadcastmb2q-2.c (test for excess errors)
UNRESOLVED: gcc.target/i386/avx512cd-vpbroadcastmb2q-2.c compilation failed
to produce executable
FAIL: gcc.target/i386/avx512cd-vpbroadcastmw2d-2.c (test for excess errors)
UNRESOLVED: gcc.target/i386/avx512cd-vpbroadcastmw2d-2.c compilation failed
to produce executable

Excess errors:
Assembler: avx512cd-vpbroadcastmb2q-2.c
        "/var/tmp//ccs_9lod.s", line 42 : Invalid instruction argument
        Near line: "    vpbroadcastmb2q %k0, %zmm0"

Assembler: avx512cd-vpbroadcastmw2d-2.c
        "/var/tmp//ccevT6Rd.s", line 35 : Invalid instruction argument
        Near line: "    vpbroadcastmw2d %k0, %zmm0"

This seems to be an as bug, but given that this rarely if ever gets any
fixes these days, this test just skips the affected tests.

Adjuststing check_effective_target_avx512cd instead doesn't seem
sensible since it would disable quite a number of working tests.

Tested on i386-pc-solaris2.11 (as and gas) and x86_64-pc-linux-gnu.
