[AArch64] Make width of stack protector guard value load configurable. (#195379) Certain embedded targets store the value of the stack protector global in an MMIO register, which requires a load of a specific width. Allow changing the backend to emit a 4-byte load for the value of the stack protector, instead of an 8-byte load. (Or vice versa for an ilp32 target.) The current version of the patch has a limitation: it still allocates a pointer-sized stack slot for the guard. This could be fixed in the future, if it becomes relevant.

Welcome to Clang.
This is a compiler front-end for the C family of languages (C, C++ and Objective-C) which is built as part of the LLVM compiler infrastructure project.
Unlike many other compiler frontends, Clang is useful for a number of things beyond just compiling code: we intend for Clang to be host to a number of different source-level tools. One example of this is the Clang Static Analyzer.
If you're interested in more (including how to build Clang) it is best to read the relevant websites. Here are some pointers:
