Revert "fixes resolving aligment of child type in slice"
...
This reverts commit aa60d2a688c965dcccf8e2c42afe5c180daba8fc.
The copyright ownership of this 10 line patch is under dispute.
See #2701 for details. So I'll revert it and then fix it myself without
looking at this patch.

inferred comptime values rather than elided scopes
...
because of this example:
```zig
export fn entry(b: bool) usize {
var runtime = [1]i32{3};
comptime var i: usize = 0;
inline while (i < 2) : (i += 1) {
const result = if (i == 0) [1]i32{2} else runtime;
}
comptime {
return i;
}
}
```
The problem is that the concept of "resetting" a result location,
introduced in the previous commit, cannot handle elision scopes.
This concept is inherently broken with inline loops.

fix @export for arrays not respecting the symbol name
...
Previously, the symbol name parameter of `@export` would be ignored for
variables, and the variable name would be used for the symbol name.
Now it works as expected.
See #2679

fix @export for arrays and allow sections on extern variables
...
previously `@export` for an array would panic with a TODO message.
now it will do the export. However, it uses the variable's name
rather than the name passed to `@export`. Issue #2679 remains open
for that problem.
