82dee4839755bf02b6366be4528a76b2d4f44be9 llvm-undname: Tweak arena allocator
- Make `allocUnalignedBuffer` look more like `allocArray` and `alloc`.
No behavior change.
- Change `Head->Used < Head->Capacity` to `Head->Used <= Head->Capacity`
in `allocArray` and `alloc`. No intended behavior change, might be a
minuscule memory usage improvement. Noticed this since it was the logic
used in `allocUnalignedBuffer`.
- Don't let `allocArray` alloc too small buffers for names that have
more than 512 levels of nesting (in 64-bit builds). Fixes a heap
buffer overflow found by oss-fuzz.
