stage2: Teach Liveness that safety checks do not modify memory
...
This change adds to Liveness a simple pattern match for the
try-like `.condbr` blocks emitted by Sema's safety checks. This
allows us to determine that these do not modify memory, which
permits us to elide additional loads in the backend.
As @Vexu points out in the main issue, this is probably not a
complete solution on its own. We'll still want a way to reliably
narrow the load/copy when performing several consecutive accesses,
such as `foo.arr[x][y].z`

Compilation: revert asking for exclusive locks on cache hits
...
We definitely want a shared lock on a cache hit. Without this, we get a
deadlock when Zig is asked to compile the same C source file multiple
times as part of the same compilation.
This is a partial revert of 8ccb9a6ad327a4d7fbc321b33d4aa66a27a1f5ee.

CBE: fix compiling for aarch64-windows
...
These bugs were triggered in the C backend by aarch64-specific code in
os/windows.zig. Intentionally not updating zig1.wasm yet because of
upcoming changes and since aarch64-windows is not tested on master yet.
