35c86984a6 cbe: support rendering union values that have no defined tag type 
This was regressed in d657b6c0e2, when
the comptime memory model for unions was changed to allow them to have
no defined tag type.

f10499be0a sema: analyze field init bodies in a second pass 
This change allows struct field inits to use layout information
of their own struct without causing a circular dependency.

`semaStructFields` caches the ranges of the init bodies in the `StructType`
trailing data. The init bodies are then resolved by `resolveStructFieldInits`,
which is called before the inits are actually required.

Within the init bodies, the struct decl's instruction is repurposed to refer
to the field type itself. This is to allow us to easily rebuild the inst_map
mapping required for the init body instructions to refer to the field type.

Thanks to @mlugg for the guidance on this one!

e74ced21b7 frontend: fix -fsingle-threaded default detection logic 
The logic in 509be7cf1f assumed that
`use_llvm` meant that the LLVM backend would be used, however, use_llvm
is false when there are no zig files to compile, which is the case for
zig cc. This logic resulted in `-fsingle-threaded` which made libc++
fail to compile for C++ code that includes the threading abstractions
(such as LLVM).

9e81222d92 zig reduce: some adjustments to make it go faster 
* don't reset the rng. it seems like it was getting stuck trying the
  same transforms over and over again.
* slide the window over after failing a large transform set, idea being
  that transformations in the failed set are more likely to be
  problematic.
