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.

Test: adb shell /data/nativetest64/bionic-unit-tests/bionic-unit-tests --gtest_filter=*tls*

4358d53cd9 Move the ILP32 mmap() hackery into legacy_32_bit_support.cpp. 
Every time I look at mmap.cpp, I fail to realize it's only built for ILP32.

Also improve some of the commentary in SYSCALLS.TXT and legacy_32_bit_support.cpp.

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!

86968d95f1 setjmp_test: riscv64 does have callee-save fp registers. 
The setjmp implementation is correct, but this comment was wrong, and we were missing the implementation of the test. This would be slightly simpler if we enabled Zfa in the build system and qemu, but this works for now.

78706d25d0 <stdio.h>: warn on some unused results. 
This is fairly conservative, touching only those functions (such as feof()) where it's clearly an error to not use the return value.

Also fix a test that was ignoring the return value of feof() (because it was just checking whether the function could take the lock, and genuinely didn't care about the result).
