__ pop(eax);
...
__ push(eax);
to enable push/pop eliminations.
__ push(eax) must happen before RecordWrite because RecordWrite may destroy
eax value. To be safe, also moved __ push(r0) on ARM to above RecordWrite.
This only affects the case where a context variable is used in a inner scope.
Create a tests for it. It fails if __ push(eax) is after RecordWrite.
