LC 331655182d ThreadManager: Fix error return values in FrontendAllocateSlots()
If ftruncate or the mmap ever fail for whatever reason, then we need to
return the current size, rather than the new size.

LC 046750354e x32/FD: Make use of SanitizeIOCount for vector construction in vmsplice
Makes this consistent with the other fd syscalls that make temporary
buffers.

LC 126be45ed1 x32/FD: Correct total word calculation in select() variants
Previously this would result in a larger amount of words specified than
necessary.

e.g. Given nfds = 1:

With AlignUp(1, 32) / 4, we'd end up with supposedly eight words, when it
should only be one word.

On the other extreme, given a full fd set of 1024 fds, then we'd end up
with 256 words, when it should only be 32.

LC e021a55abd BPFEmitter: Amend instruction class checking in HandleStore()
This was previously checking for a load class, which would result in ST
clobbering the index register.

LC 2ad6254894 x64/Thread: Amend faulting copy handling related to LDTs
CopyToUser doesn't return the number of bytes copied, but rather returns
0 to indicate success, otherwise a fault has occurred (and the SIGSEGV
handler has set X0 to EFAULT)
