All non-resource variable declarations in the global scope are implicitly added to `$Global` constant buffer.
The declarations can have an explicit layout specifies by using the ` : register(c#)` annotation. This task is to track implementation of the explicit layout of `$Globals` constant buffer.

For this global constants:
```
int a;
float b : register(c1);
```
The buffer layout should look like this:
```
cbuffer $Globals
{
struct $Globals
{
int a; ; Offset: 20
float b; ; Offset: 16
} $Globals; ; Offset: 0 Size: 24
}
```
The declarations without `register(c#)` annotations are placed in the buffer after the explicit ones.
