Suppress _dl_runtime_resolve_avx_slow for memcheck conditional.
glibc ld.so has an optimization when resolving a symbol that checks
whether or not the upper 128 bits of the ymm registers are zero. If
so it uses "cheaper" instructions to save/restore them using the xmm
registers. If those upper 128 bits contain undefined values memcheck
will issue an Conditional jump or move depends on uninitialised value(s)
warning whenever trying to resolve a symbol.
This triggers in our sh-mem-vecxxx test cases. Suppress the warning
by default.
