1195994880 fix inability to write to global in some cases 
before, when we initialized a variable by copying the
initialization value, it made the internal const value
references point to a duplicate value, resulting in
a phony duplicate global value being updated instead of
the real on. now the behavior is as expected.

thanks to hoppetosse for pointing out this bug on IRC.

b78c91951a remove ability to mark if and switch as inline 
if and switch are implicitly inline if the condition/target
expression is known at compile time.

instead of:

```
inline if (condition) ...
inline switch (target) ...
```

one can use:

```
if (comptime condition) ...
switch (comptime target) ...
```

2f259b8176 IR: re-organize where state goes to prepare for generics 
* Rip out legacy code for generics
 * put scope in instruction instead of AST nodes
 * separate top level decl stuff from AST nodes
   - remove the assumption that there is a 1:1 correspondence
     between an output instruction and an AST node
   - This way we won't have to clone AST nodes for generics.
