x86-64: optionally use GS segment as thread base
Use #+gs-segment-thread feature to enable.
This will need performance testing. Allocations take at least 25 bytes more
to encode because of the segment override prefix (which incurs extra latency
from my understanding) and the 4-byte displacement for memory absolute
addressing mode.
