25c53f08a6 elf: redo strings management in the linker 
* atom names - are stored locally and pulled from defining object's
  strtab
* local symbols - same
* global symbols - in principle, we could store them locally, but
  for better debugging experience - when things go wrong - we
  store the offsets in a global strtab used by the symbol resolver

a2f4adbd19 zig reduce: add "delete unused globals" transform 
While walking the AST looking for reductions, notice if any globals are
unreferenced, and if they are, add a transformation for removing the
global.

1396479656 zig reduce: redesign 
Now it works like this:
1. Walk the AST of the source file looking for independent
   reductions and collecting them all into an array list.
2. Randomize the list of transformations. A future enhancement will add
   priority weights to the sorting but for now they are completely
   shuffled.
3. Apply a subset consisting of 1/2 of the transformations and check for
   interestingness.
4. If not interesting, half the subset size again and check again.
5. Repeat until the subset size is 1, then march the transformation
   index forward by 1 with each non-interesting attempt.

At any point if a subset of transformations succeeds in producing an interesting
result, restart the whole process, reparsing the AST and re-generating the list
of all possible transformations and shuffling it again.

As for std.zig.render, the fixups operate based on AST Node Index rather
than Nth index of the function occurence. This allows precise control
over how to mutate the input.

f6de3ec963 zstandard: fix incorrect RLE decompression into ring buffer 
This reverts a change introduced in #17400 causing a bug when
decompressing an RLE block into a ring buffer.

RLE blocks contain only a single byte of data to copy into the output,
so attempting to copy a slice causes buffer overruns and incorrect
decompression.

1ccc68f307 frontend: rip out Decl dependencies 
This incremental compilation logic will need to be reworked so that it
does not depend on buried pointers - that is, long-lived pointers that
are owned by non-top-level objects such as Decl.

In the meantime, this fixes memory leaks since the memory management of
these dependencies has bitrotted.
