Mapping a direct memory range that includes an unallocated physical
page threw std::invalid_argument and ended the process. It now returns
ENOMEM before anything is mapped, as shadPS4's MemoryManager::MapMemory
does.

KytyPS5 and shadPS4 return EFAULT for a null name. The test keeps that
and the rename and clear checks, and drops the null address, zero length
and past-the-end cases that no reference covers; the debt entry records
them as unknown, with the 32-byte name limit.

On Windows a sleep shorter than TimedWait's 0.5 ms lead, and the last 0.5 ms of a longer one, is a YieldProcessor spin in host code with no wait counted. A raise that found the target there could only be delivered through the return-address breakpoint or sampling, so sceKernelRaiseException at a thread looping on such sleeps was lost: a thread looping on sceKernelUsleep(200) lost the first raise in 5 of 5 runs.
The spins in SleepUntil and SleepNanosUnlessChanged now run under a DeliveryDeferral and drain APCs afterwards, as BeginPark and Unpark already do. A raise that finds the target spinning is queued as an APC and runs when the sleep ends.
GuestRaiseShortSleep raises 100 times each at a thread sleeping 100, 200 and 400 us in a loop, with sleep wakes on (SleepNanosUnlessChanged) and with APS5_NO_SLEEP_WAKE (SleepUntil). Both fail on main at the first or second raise.

Emscripten targets wasm64 without x86 assembly, Linux-only headers or the
x87 long double. These changes add __EMSCRIPTEN__ paths beside the host
ones; native builds compile the same code as before.
- libc: long doubles in guest varargs and scanf go through
GuestLongDouble, a plain copy where long double is the x87 format;
APS5_EXPORT emits no assembler alias; the guest arena is one aligned
allocation that zeroes pages when they are committed again; getifaddrs
keeps its link-level entries on Linux; /proc lookups and the host
stderr duplicate are left out.
- libkernel: file-backed mmap, EVFILT_VNODE watches, getcontext and
setcontext throw; getdents replaces the raw getdents64 syscall;
getdtablesize takes the resource limit alone.
- VideoOut leaves SDL, the display window and the HDR probe out,
Sysmodule asks libkernel for unwind information and Net includes
sys/time.h.
host_performance_session_tests uses no guest library, so the guest unwind helper leaves the C++ runtime unlinked on MinGW and the link fails with an undefined __gxx_personality_v0. The host test helper links the runtime statically, as the other host-only tests do.
On Windows, sceKernelRaiseException threw for a thread created suspended
and not resumed yet. FreeBSD libthr starts such a thread with signals
blocked and restores its mask on resume, so the signal stays pending and
is delivered on that thread once it runs.
The raise is now recorded in the thread's pendingException with a
compare-exchange, and the thread exchanges it for -1 when it leaves the
creation wait and delivers it to itself before its start routine. Both
sides use one atomic, so a raise racing a resume is either taken by the
thread or, after it started, delivered as for a running thread. Raises
while pending are merged, as for a standard signal.
guest_pthread_create_suspended now runs the deferred-delivery case on
every host, with a second raise while the thread is suspended.
