Martin Kustermann 4ea512b4c1 [llvm_codegen] Use exclusively SExpression support from VM and nothing else. 
The LLVM code generator should only consume the serialized IR and not use any other VM functionality.
This CL adds a custom zone which can be used for the deserialized IR nodes and removes any
Dart_SetVMFlags/Dart_Initialize/ApiZone/... calls.

This works with the existing example:

    % ninja -C out/ReleaseX64 codegen
    % out/ReleaseX64/codegen runtime/llvm_codegen/test/codegen/Inputs/hello.sex
    ...
    define void @"hello.dart::main"() {

    B1:
      %0 = call i8* @llvm.stacksave()
      %1 = ptrtoint i8* %0 to i64
      %2 = load i64, i64 addrspace(256)* inttoptr (i64 72 to i64 addrspace(256)*)
      %3 = icmp ult i64 %1, %2
      br i1 %3, label %4, label %5
      ...
      ret void
    }
    ...

Jake Ehrlich 87b0dbab2d [llvm_codegen] Contrived hello world 
This change adds enough functionality to compile hello world
from S-expressions in a contrived way. It fails to handle this input
realistically in several ways.

1) It assumes the existence of dart:core::print
2) It handles all dart values as C strings
3) It assumes only very static calls can be made with no named arguments
4) If a stack overflow is detected it just traps.
5) I'm not sure how the current dart runtime works but the contrived runtime
   used here puts a contrived thread object in `gs`.

This change adds a basic framework for implementing new instructions that
should make it possible to implement new instructions with much smaller
changes however.

Jake Ehrlich 45172f0690 Revert "Reland "[llvm] Add initial scaffolding"" 
This reverts commit 524fdc13a9.

Reason for revert: I still broke flutter somehow. I got the same error. Looking into it now.
