back-out the back-out for this branch.  yay.

Backing out this merge that I pushed (prematurely) to the wrong place.

Reviewed by Nyx.

Better usage of LLVertexBuffer::sEnableVBOs.
Added RenderUseStreamVBO debug setting for controlling usage of VBOs for particles/avatars/etc.

Backed out changeset useVBO fix, 12f94ed4e02b, "LLVertexBuffer only supposed to use sEnableVBOs at moment vert buff is created" for EXT-7835.  Will fix soon.

Extra validation on vertex buffers.

16-byte aligned vertex buffers.
(almost) fully vectorized avatar vertex buffer updating --- index buffers still need to be vectorized

Added RenderUseStreamVBO to enable/disable usage of VBO's for streaming buffers.
Faster traversal of LLCullResult members.
Removal of llpushcallstacks from inner loops.
Sprinkling in fast timers.
