Ryan Houdek 0d33dacc37 unittests/ASM: Implements a unit test for #3478 
This unit test recreates the error condition that #3478 causes.
With a string operation that is a backwards copy then the optimization
will read past the end of the page and result in a crash.

Seemingly only happens with backwards string operations, but test
forward and backward in this test.

Tony Wasserka f43fe5fd63 Allocator: Stop parsing more eagerly 
This is a soft-revert of eaf83aa. That change is no longer needed, since the
stack special case is handled externally now.

Tony Wasserka dce9f651fd Allocator: Split off memory gap collection to a separate function 
This function can be unit-tested more easily, and the stack special is more
cleanly handled as a post-collection step.

There is a minor functional change: The stack special case didn't trigger
previously if the range end was within the stack mapping. This is now fixed.

Alyssa Rosenzweig 92f31648b9 RCLSE: optimize out pointless stores 
can help a lot of x86 code because x86 is 2-address and a64 is 3-address, so x86
ends up with piles of movs that end up dead after translation

It's not a win across the board because our RA isn't aware of tied registers so
sometimes we regress moves. But it's a win on average, and the RA bits can be
improved with time.

Ryan Houdek 54403e2146 Disable assert in release 
Arguments and conditional doesn't get optimized out in release builds
for the inline function call versus the define.

Was showing up an annoying amount of time when testing.

Ryan Houdek aeb41e9ae2 IoctlEmulation: Add missing nouveau ioctl 
The NVIF ioctl isn't publicly described in the nouveau headers and it is
required for anything to work with Nouveau.

Pass the ioctl command through without modification and hope that this
ioctl is architecture agnostic.

Ryan Houdek 067b346e1b Removes steamwebhelper config 
Fixes #3479

As of the Steam update on Feb 29 2024, this is no longer necessary and
actually causes steamwebhelper to abort.

Steam has started using SLR to launch steamwebhelper, which already
passes in --no-sandbox. Adding this argument twice seemingly breaks the
application since it starts complaining that it doesn't understand the
argument and closes with a SIGABRT.

With this removed Steam starts working again.
