Ryan Houdek 2cac41ee1c Adds a bunch more syscalls 
Some of these are just there to get us farther in some cases. They can
result in behaviour the app isn't expecting like when signals are setup
but not handled correctly.
Is fine for the cases that the app doesn't actually use them.

Ryan Houdek 6471b6e833 Adds two new thread syscall functions

expected until signals are implemented here

Ryan Houdek 780278a7f6 Fixes memory allocation 
4GB virtual memory is too small and causes things to fault.
Previously we were at `1 << 36` but it caused oom issues on devices with
smaller amounts of memory.
This time ensure the the SHM memory is allocated with MEM_NORESERVE so
devices can actually allocate the virtual memory region.

Ryan Houdek f74bca4fdb Fixes a race condition in WaitForIdle 
This is something that TSAN caught was happening.
Grabs the thread creation mutex when checking for idle and extends the
sleep time for WaitForIdle to something that is still below unit test
run time

Ryan Houdek 9233589ccc Fixes clone syscall when VFORK flag is used 
The VFORK flag lets clone behaviour similarly to a fork.
The parent will be suspended until the resulting thread is exited
The mutex is removed because everything that touches state is already
wrapped by mutexes. So we don't need this one

Ryan Houdek 94b0ea4be3 Fixes the getaffinity syscall 
This was implemented with the glibc API originally which was incorrect.
The syscall API is just a simple bitmask of for the affinity of the
number of CPU cores and a size check that the resulting structure is
large enough to store the number of bits.

Ryan Houdek 2ec41070da Ensure that anything opened with openat is tracked in our FD map 
Missing this was an accident, this was how it was supposed to be.
It's very helpful to map FDs to filenames when tracking mmap mappings

Ryan Houdek 30bce2468d Remove magic numbers for invalid register class definition 
Consolidates usage of register class to the one that is defined in the
IR Json file.
Every magic number is replaced with InvalidClass and instead uses the
enums directly

Another bug fix is that the GetHostFlags IR ops was being declared as
using the flags register class, which isn't a real thing yet.
This would most likely have ended up with host flag usage being
scheduled to a GPR that was already scheduled and overwrite it.

Once this IR op ends up in host flags this will be changed as well

Ryan Houdek f46870a2fb Fix a bug in the const prop pass 
When a Zext is going 64bit->128bit this involves a register class change.
This is special cased in the CPU cores and the const prop class doesn't
really have a way to handle this case in the IR level
