Rewrite code for stack frame manipulation

[Maratyszcza]

Problems with the current code:

• Functionality is very complex and scattered all over the place
• There are likely bugs and/or inefficiencies
• Unclear how it works with Golang asm
• Need something like -fomit-frame-pointer
• Does not use read zone
• Inefficient addressing of storage for clobbered xmm registers when stack is realigned (store/load instructions use rsp-based addressing instead of rbp)
• Argument addressing does not switch to rbp when stack is realigned
