I can guess why this performs better: half the page table entries and thus half
the tlb entries required.  Which for any non-trivially sized jit arena is going
to add up. [*]

In line with my comments re patch 6, and making this feature available
everywhere (or at least non-windows), the ifdefs would go away.  I might also
suggest default on for CONFIG_DEBUG_TCG and otherwise default off (when the
host os allows).

* Which makes me wonder how much we should use the "const TranslationBlock *"
version of that structure in the rx mapping, so that we're using a tlb entry
that is more likely to be present, since we've just branched from the code (or
just about to branch to the code) on the same page.
