// x64 ABI:s, and helpers to help follow them when JIT-ing code.
// All convensions return values in EAX (+ possibly EDX).
// Linux 32-bit, Windows 32-bit (cdecl, System V):
// * Caller pushes left to right
// * Caller fixes stack after call
// * function subtract from stack for local storage only.
// Scratch: EAX ECX EDX
// Callee-save: EBX ESI EDI EBP
// Parameters: -
// Windows 64-bit
// * 4-reg "fastcall" variant, very new-skool stack handling
// * Callee moves stack pointer, to make room for shadow regs for the biggest function _it itself calls_
