Expand the interface of page_set_flags to separate the
set of flags to be set and the set of flags to be cleared.
This allows us to replace PAGE_RESET with the PAGE_VALID
bit within clear_flags.
Replace PAGE_TARGET_STICKY with TARGET_PAGE_NOTSTICKY;
aarch64-linux-user is the only user.

Add a user-mode emulation version of the function. More will be
added later, for now it is just process_queued_cpu_work.

All target_pt_regs which have not been broken out to
target_ptrace.h by this point are unused. Remove them.

PowerPC was the one outlier that defined both ELF_ARCH and
ELF_MACHINE; ELF_ARCH was defined incorrectly, necessitating
the definition of elf_check_arch.
However, the elf file header field in question is called
e_machine, so ELF_MACHINE is in fact the better name.
Mechanically change most target/target_elf.h files,
then adjust ppc/target_elf.h manually.
Do not provide a default for ELF_MACHINE.

Merge init_thread and target_cpu_copy_regs.
There's no point going through a target_pt_regs intermediate.

Rename from cpu_get_model to emphasize that this is an elf-specific
function. Declare the function once in loader.h.
This frees up target_elf.h for other uses.

Improve the linux-user emulation to send the correct si_code depending
on overflow (TARGET_FPE_FLTOVF), underflow (TARGET_FPE_FLTUND), ...
Note that the hardware stores the relevant flags in FP exception
register #1, which is actually the lower 32-bits of the 64-bit fr[0]
register in qemu.

"linux-user/cpu_loop-common.h" is generic enough to be used by
bsd-user, so rename it as "user/cpu_loop.h".
Mechanical change running:
$ sed -i -e 's,cpu_loop-common.h,user/cpu_loop.h,' \
$(git grep -l cpu_loop-common.h)
