When these are set the allocation permissions aren't actually updated.

Alyssa Rosenzweig f0a434c167 IR: inline as we go 
Augment IREmitter to inline constants as we generate code, rather than
needing a later clean up pass. This replaces the last function of ConstProp.

Billy Laws c8cecd9f46 Frontend: Adjust forward branch distance limit 
Now executable page tracking is implemented, this limit is technically
unnecessary and effectively never hit in normal code. Keep a reasonable
limit however to avoid accidentally inlining tail calls and exploring
dead branches in obfuscated code.

Ryan Houdek 572e5ed9c6 HostRunner: Fixes bug with saving CSFSGS 
We were failing to save the entire 64-bit register, cutting off the top
32-bits which contain SS and CS. This ...happened to not cause issues
but is a bug that I encountered with far jump handling.

Changwei Miao 0293d2027d LinuxEmulation: add basic supports for v4l2 driver of wine32. 
This patch does cover up all v4l2 syscalls in i386. It just works
well with the poor v4l2 driver of wine32.
