Skyler Saleh 76ed9310f2 Apple M1: RAII Wrapper for JITPageWrite*Execute*()
Added RAII wrapper around the the JITPageWriteEnableExecuteDisable() and
JITPageWriteDisableExecuteEnable() to make it so that it is harder to forget to
pair the calls in all code branches as suggested by leoetlino.

Skyler Saleh 948764d37b Apple M1: Build, Analytics, and Memory Management
Analytics:
- Incorporated fix to allow the full set of analytics that was recommended by
  spotlightishere

BuildMacOSUniversalBinary:
- The x86_64 slice for a universal binary is now built for 10.12
- The universal binary build script now can be configured though command line
  options instead of modifying the script itself.
- os.system calls were replaced with equivalent subprocess calls
- Formatting was reworked to be more PEP 8 compliant
- The script was refactored to make it more modular
- The com.apple.security.cs.disable-library-validation entitlement was removed

Memory Management:
- Changed the JITPageWrite*Execute*() functions to incorporate support for
  nesting

Other:
- Fixed several small lint errors
- Fixed doc and formatting mistakes
- Several small refactors to make things clearer

Skyler Saleh 4ecb3084b7 Apple M1 Support for MacOS
This commit adds support for compiling Dolphin for ARM on MacOS so that it can
run natively on the M1 processors without running through Rosseta2 emulation
providing a 30-50% performance speedup and less hitches from Rosseta2.

It consists of several key changes:

- Adding support for W^X allocation(MAP_JIT) for the ARM JIT
- Adding the machine context and config info to identify the M1 processor
- Additions to the build system and docs to support building universal binaries
- Adding code signing entitlements to access the MAP_JIT functionality
- Updating the MoltenVK libvulkan.dylib to a newer version with M1 support

Shawn Hoffman f206a4ea9c remove MemUsage, and therefor psapi dependency 2017-06-08 22:25:46 -07:00
JosJuice 4b4cf509f8 Remove code for only allocating low memory
This is unnecessary when we have position-independent code.

Léo Lam 5d00915d37 MemoryUtil: Fix formatting
clang-format really *wants* the two empty lines to be removed;
otherwise, it will always flag MemoryUtil as needing formatting changes
which is an annoyance when it is used as a git filter driver.

degasus 562b9d4a9f VideoCommon: Abort texture prefetching on low RAM
There is no nice way to correctly "detect" the "used" memory, so we just say
we're fine to use 50% of the physical memory for custom textures.

This will fix out-of-memory crashes, but we still might run into swapping issues.

comex 7ad9027593 Be pedantic about stack overflow on Linux and OS X.
Add some magic to the fault handler to handle stack overflow due to BLR
optimization, and disable the optimization if fastmem is not enabled.
