Add MIPS-specific prctl() options TARGET_PR_SET_FP_MODE and
TARGET_PR_SET_FP_MODE. These values are essentially copied from
linux kernel header include/uapi/linux/prctl.h.
This is done in a way consistent with a similar case of
aarch64-specific prctl() options TARGET_PR_SVE_SET_VL and
TARGET_PR_SVE_GET_VL.

Regarding R5900 CPU, some sources indicate that the Emotion Engine
ISA/ASE was designed by Toshiba and licensed to Sony. Others sources
claim it was a joint effort. It therefore makes sense to refer to
the CPU as "Toshiba/Sony R5900".
Also, remove and "'s" in the line for some other CPU, for the sake
of consistency.

This isn't necessary in QEMU, because (even if the guest

Our __get_user_e() and __put_user_e() macros cause newer versions
of clang to generate false-positive -Waddress-of-packed-member
warnings if they are passed the address of a member of a packed
struct (see https://bugs.llvm.org/show_bug.cgi?id=39113).
Suppress these using the _Pragma() operator. Unfortunately
_Pragma() support in gcc is broken in some gcc versions and
in some usage contexts, so we limit the pragma usage here to clang.
To put in the pragmas we need to convert the macros from
expressions to statements, but all the callsites effectively
treat them as statements already so this is OK.

On PCXS chips (PA7000, pa 1.1a), trap #18 is raised on memory faults,
while all later chips (>= PA7100) generate either trap #26, #27 or #28
(depending on the fault type).
Since the current qemu emulation emulates a B160L machine (with a
PA7300LC PCX-L2 chip, we should raise trap #26 (EXCP_DMAR) instead
of #18 (EXCP_DMP) on access faults by the Linux kernel to page zero.
With the patch we now get the correct output (I tested against real
hardware):
Kernel Fault: Code=26 (Data memory access rights trap)
instead of:
Kernel Fault: Code=18 (Data memory protection/unaligned access trap)

GNU make is perfectly happy to use 'check-FOO-y += bar' to
initialize check-FOO-y. (GNU Automake strictly insists that
you cannot use += until after an initial = per variable, but
thankfully we aren't using automake).
As we have had more than one instance where copy-and-paste of
'check-FOO-y = bar' from a first test under category FOO into
an additional test, which ends up disabling the first (see
commits 992159c7 and 4429532b), it's better to just always use
the form that survives copy-and-paste, even for categories that
don't currently add more than one test.
