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

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.

wasm: fix bitcasting to -and from arrays 
Arrays are currently always passed by reference, this means that we
always keep the value in linear memory and never load it to Wasm's
stack. Scalar values however do get lowered to Wasm's stack.
This means when bitcasting from an array to a scalar value, we must
load the memory of the array as such scalar type. To bitcast
a scalar type to an array, we allocate a new temporary in the
linear data segment, and then store the scalar value there.

d890e81761 mem: fix ub in writeInt 
Use inline to vastly simplify the exposed API.  This allows a
comptime-known endian parameter to be propogated, making extra functions
for a specific endianness completely unnecessary.

4d044ee7e0 sema: Add union alignment resolution 
- Add resolveUnionAlignment, to resolve a union's alignment only, without triggering layout resolution.
- Update resolveUnionLayout to cache size, alignment, and padding. abiSizeAdvanced and abiAlignmentAdvanced
  now use this information instead of computing it each time.
