This series aims to improve TCACHE performance in memory allocator:
simplify TCACHE code path in free() and add TCACHE support for calloc().

---
Changes in v2:
- _int_free_check() should be put outside of USE_TCACHE.
- Merge tst-safe-linking fix into commit#5 to make sure CI check pass.
- Link to v1: https://sourceware.org/pipermail/libc-alpha/2024-August/159357.html

Wangyang Guo (5):
  malloc: Split _int_free() into 3 sub functions
  malloc: Avoid func call for tcache quick path in free()
  malloc: Arena is not needed for tcache path in free()
  benchtests: Add calloc function test to bench-malloc-thread
  malloc: Add tcache path for calloc
