    [compiler] Remove LoadStackPointer and related machinery · 5b2ab2f6
    Jakob Gruber authored
    Now that all uses of LoadStackPointer have been removed, this CL cleans
    up related code:
    
    - Removed LoadStackPointer.
    - Removed ArchStackPointer.
    - Removed IA32StackCheck.
    - Removed X64StackCheck.
    - Removed StackCheckMatcher.
    
    All stack checks now follow a simple path without matchers or special
    register constraints: they load the limit and pass it to
    StackPointerGreaterThan, which is finally handled by code generation.
