MCA enums make it easier for users to see/set MCA flag values. Also add "op_avx_capabilities" read-only MCA var that shows what is supported on your platform, regardless of what value the user has set in "opal_avx_support". For example, ompi_output shows all the valid values: ``` $ ompi_info --all --parsable | grep _avx_ mca:op:avx:param:op_avx_capabilities:value:SSE,SSE2,SSE3,SSE4.1,AVX mca:op:avx:param:op_avx_capabilities:source:default mca:op:avx:param:op_avx_capabilities:status:read-only mca:op:avx:param:op_avx_capabilities:level:4 mca:op:avx:param:op_avx_capabilities:help:Level of SSE/MMX/AVX support available in the current environment mca:op:avx:param:op_avx_capabilities:enumerator:value:1:SSE mca:op:avx:param:op_avx_capabilities:enumerator:value:2:SSE2 mca:op:avx:param:op_avx_capabilities:enumerator:value:4:SSE3 mca:op:avx:param:op_avx_capabilities:enumerator:value:8:SSE4.1 mca:op:avx:param:op_avx_capabilities:enumerator:value:16:AVX mca:op:avx:param:op_avx_capabilities:enumerator:value:32:AVX2 mca:op:avx:param:op_avx_capabilities:enumerator:value:256:AVX512F mca:op:avx:param:op_avx_capabilities:enumerator:value:512:AVX512BW mca:op:avx:param:op_avx_capabilities:deprecated:no mca:op:avx:param:op_avx_capabilities:type:int mca:op:avx:param:op_avx_capabilities:disabled:false mca:op:avx:param:op_avx_support:value:SSE,SSE2,SSE3,SSE4.1,AVX mca:op:avx:param:op_avx_support:source:default mca:op:avx:param:op_avx_support:status:read-only mca:op:avx:param:op_avx_support:level:4 mca:op:avx:param:op_avx_support:help:Level of SSE/MMX/AVX support to be used, capped by the local architecture capabilities mca:op:avx:param:op_avx_support:enumerator:value:1:SSE mca:op:avx:param:op_avx_support:enumerator:value:2:SSE2 mca:op:avx:param:op_avx_support:enumerator:value:4:SSE3 mca:op:avx:param:op_avx_support:enumerator:value:8:SSE4.1 mca:op:avx:param:op_avx_support:enumerator:value:16:AVX mca:op:avx:param:op_avx_support:enumerator:value:32:AVX2 mca:op:avx:param:op_avx_support:enumerator:value:256:AVX512F mca:op:avx:param:op_avx_support:enumerator:value:512:AVX512BW mca:op:avx:param:op_avx_support:deprecated:no mca:op:avx:param:op_avx_support:type:int mca:op:avx:param:op_avx_support:disabled:false ``` Signed-off-by: Jeff Squyres <jsquyres@cisco.com> (cherry picked from commit 566412e)
