Tweak BumpPtrAllocator to benefit the hot path (#90571)
This takes the form of three consecutive but related changes:
- Mark the fast path of BumpPtrAllocator as likely-taken.
- Move the slow path of BumpPtrAllocator to a separate function.
- Mark the slow path of BumpPtrAllocator as noinline.
Overall, this saves geomean 0.4% userspace instructions on CTMark -O3,
and 0.98% on CTMark -O0 -g.
