remove a stage2 test case that relies on a very deep compiler stack
...
It's causing Drone CI failure on aarch64. I will open a follow-up issue
to track this missing test case.

AstGen: avoid redundant "ref" instructions
...
Whenever a `ref` instruction is needed, it is created and saved in
`AstGen.ref_table` instead of being immediately appended to the current
block body. Then, when the referenced instruction is being added to the
parent block (e.g. from setBlockBody), if it has a ref_table entry, then
the ref instruction is added directly after the instruction being referenced.
This makes sure two properties are upheld:
1. All pointers to the same locals return the same address. This is required
to be compliant with the language specification.
2. `ref` instructions will dominate their uses. This is a required property
of ZIR.
A complication arises when a ref instruction refs another ref
instruction. The logic in appendBodyWithFixups must take this into
account, recursively handling ref refs.

LLVM: handle extern function name collisions
...
Zig allows multiple extern functions with the same name, and the
backends have to handle this possibility.
For LLVM, we keep a sparse map of collisions, and then resolve them in
flushModule(). This introduces some technical debt that will have to be
resolved when adding incremental compilation support to the LLVM
backend.

Revert "Treat blocks with "return" as "noreturn""
...
This reverts commit 135b91aecd9be1f6f5806b667e07e383dd481198.
"endsWithBreak()" is not a meaningful question to ask and should not be
used this way. A simple example that defeats this logic is:
```zig
export fn entry() void {
outer: {
{
break :outer;
}
return;
}
}
```

Treat blocks with "return" as "noreturn"
...
Block statements that end with "break" should not be considered
"noreturn" for the enclosing scope, but other "noreturn" instructions
(return, panic, compile error, etc.) should be. This differentiation
necessitates handling "break" differently from the other "noreturn"
instructions when inside a block statement.
