1. Update musl to 1.1.15 (#4813) …

   * Revert all emscripten musl changes
   
   * Update musl to 1.1.5
   
   * Reapply emscripten patches
   
   * Fix up libs to partially compile
   
   * Revert emscripten musl include folder
   
   * Update musl include folder to 1.1.5
   
   * Reapply emscripten libc include changes
   
   * Get compiling again!
   
   * Restore alltypes.h to have emscripten-specific changes
   
   alltypes.h is autogenerated, and we've since overridden the types
   
   Longer-term, we should figure out a way to either autogenerate the types
   to match what emscripten expects, or change emscripten's expectation to
   support musl's assumptions. Probably worth including with merging the
   asm&wasm ABIs.
   
   * Update expected langinfo test output for fixes in upstream musl
   
   * Canonicalize nans in hyperbolic test
   
   Nans are now printed out with their sign if negative. Asm and wasm treat
   these differently, so canonicalize how they print.
   
   * Tweak how musl forwards syscalls to emscripten
   
   Before: pass all syscall args as varargs, args are int32
   After: cast all syscall args to int32, pass as varargs
   This fixes and prevents aliasing issues, and is more consistent with
   other architectures
   
   * Change __syscall to syscall in isatty to set errno
   
   POSIX specifies that isatty sets errno in the case that it fails.
   __syscall doesn't set errno, and syscall does.
   
   * Update struct_info again
   
   * Always allocate pthread_self, even in the stub
   
   * sys_open should call __syscall_ret
   
   * Fix up pthread js for optimized code (remove __asm: true)
   
   * Canonicalize more nans in testsuite
   
   * Re-set expected langinfo output
   
   * Update align_moar expected addresses
   
   * Disable assert in wasm_backend llseek syscall
   
   * Update now-passing wasm_backend tests
   
   * Update other.test_locale to non-stub setlocale
   
   * Fix compiling with -s USE_PTHREADS=1
   
   * Initialize __pthread_self() when using pthread_stub
   
   * Canonicalize nans for test_zerodiv
   
   * Update count of globals in test_dlfcn_self
   
   * Rework how we initialize pthread_self for non-threaded applications
   
   * Prefer 'EMSCRIPTEN_START_FUNCS' in test_memorygrowth, because 'var TOTAL_MEMORY' can move around
   
   * Now that CURRENT_LOCALE isn't reading off NULL, test_langinfo should expect ASCII
   
   * Re-disable test_demangle_stacks - was spuriously passing earlier
   
   * Explicitly pass 0 as the high bits for SYS__llseek
   
   * Enable v8 for test_readdir now that it supports printErr
   
   * Only use __syscall_emscripten if __EMSCRIPTEN__ is defined
   
   * Move O_LARGEFILE as default back to libc
   
   * libc #if to #ifdef
   
   * Rename pthread import funcs to not rely on alias
   
   * Consistently reference pthread_setcancelstate by alias in libc
   
   * Stub out fcntl64 for NO_FILESYSTEM case
   
   * Update emscripten-specific pthread struct fields
   
   * Consistently reference pthread_testcancel by alias in libc
   
   * Stub out SYS_rt_sigqueueinfo syscall
   
   * Stub out SYS_sendmmsg syscall
   
   * Stub out SYS_recvmmsg syscall
   
   * Revert "Consistently reference pthread_testcancel by alias in libc"
   
   This reverts commit 43563a5.
   
   * Revert "Consistently reference pthread_setcancelstate by alias in libc"
   
   This reverts commit 2ca2ede.
   
   * Correctly fix unresolved symbol: __pthread_setcancelstate
   
   * Update library_pthread.c pthread_testcancel to match musl's expectations
   
   * test_strftime.c -> test_strftime.cpp
   
   * library_pthread_stub pthread_exit should call exit, not nothing
   
   * TEMP: init pthread_self->locale with pthreads enabled
   
   * Initialize pthread global data from libc in JS
   
   * Move _b_lock and _b_waiters back to not emscripten-only
   
   * Remove untrue __asm annotation from threaded pthread_self, make stub pthread_self non-asm
   
   * Remove old unneeded pthread init exported functions
   
   * Move pthread_self in stub case to libc C code
   
   * Move emscripten_pthread initialization to its own file, out from locale_map.c
   
   * Statically allocate the pthread struct and not just a pointer in the stub case
   
   * Remove commented-out test args
   
   * Remove misleading __asm annotation for _register_pthread_ptr
   
   * Do module-side pthread initialization in-module
   
   * Don't cast away volatile when calling emscripten_futex_wake in __wake
   
   * Expose libc struct to emscripten, use that for non-main pthread initialization
   
   * Re-add pthread_impl.h import to library_pthread.c
   
   * Update align_moar alignment post-rebase
   
   * Update emscripten header include in libc.c
   
   * Remove obsolete locale preallocating code in newlocale
   
   We previously statically allocated a single locale in the event that
   we needed to dynamically allocate one during startup. musl changed their
   implementation to statically allocate C_LOCALE and UTF8_LOCALE, so we
   already get that behavior.
   In addition this was causing invalid locales to get allocated instead of
   returning NULL, because the preceding logic changed. That was caught by
   other.test_locale_wrong
   
   * Update test_llvm_lto
   
   * Bump version to 1.37.5
