Update lang.
Respect dstSize and truncate in ccc string conv.

All of these funcs were not null terminating, oops.  And they were also
ignoring dstSize, so if the game specified one it would overflow.
Fix another race condition with multithreading.

It's possible that after it's marked completed, the CPU will grab it to
enqueue.  This actually happened to mean with decent reproducibility.
Fix GL errors / flicker in framebuf->mem.

Happens in Tales of Phantasia X, reported by Kingcom.
Use SSE some in framebuffers to memory.

Since people are using it (even though it seems dangerous), might as well
make it faster.  6% better in Tales of Phantasia X.
Add memchecks for ELF loading.

Helps in games that use modules.
Upgrade symbolmaps with module address info.

This fixes some issues with jit replacement only if you had a map laying
around.
Ignore when a proxied block points to erased mem.

Happens for example when a new module is loaded, sometimes.
