Reason for revert:
Broke Node.js tests (test-require-dot etc.)

When parsing a eagerly-parsed-but-lazily-compiled function, we
used to put some of its AST nodes into a discardable Zone. This
CL puts the function Scope, its inner Scopes and the related AST
nodes (Declarations, VariableProxys) into the temporary Zone
too. This reduces peak memory usage and enables future work to
keep the temporary Zone around for later compilation.

__ 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.
