82b033271d Move the ILP32 mremap() hackery into legacy_32_bit_support.cpp. 
Similar to mmap(), this confuses me every time I look at it. Move it out
of the way, and make it clearer that this is just junk that can be
deleted when we remove 32-bit support.

Also improve coverage by adding a test for the varargs special case.

c221beccc1 Add a missing riscv64 psabi constant. 
Also group all the RELR/arm64/riscv64 bits together rather than mixing them up slightly as we'd done so far.

4d4377881d [riscv][bionic] Prototype TLS Descriptor support 
Add basic assembly stubs for TLS Descriptor support in the dynamic
linker, and enable several code paths related to TLSDESC for RISC-V.

Note: This patch requires an updated toolchain that supports TLSDESC
for RISC-V, and the `-mtls-dialect=` compiler option specifically.

ad44152c38 new.cpp: add sized operator delete. 
clang-19 and later default to C++14 sized deallocation. Currently we don't have C23's C equivalent of free_sized(), so we just implement these in terms of free() for now.

69ddb74135 <malloc.h>: warn on unused results for malloc_usable_size(). 
Not a security problem, but definitely a bug if you're calling this and ignoring the result, since it has no side-effects.

(All of the more important functions -- realloc() especially -- are already annotated.)

4e63125ce1 getpagesize(): remove "portability" claim. 
This is just POSIX nonsense. Android, iOS/macOS, the BSDs, and glibc all have getpagesize(). Window doesn't, but Windows doesn't have sysconf(3) either, so there's not a strong "portability" argument to be had there!
