The new sigfpe-eh.c fails with
internal compiler error: RTL check: expected elt 0 type 'e' or 'u', have 'w' (rtx const_int)
This is most likely due to a typo: XEXP (*op1, 0) was used, when
XEXP (*op0, 1) was intended. This did not cause any user-visible
problems, because reversed_comparison_code_parts ignores the
respective argument, and the release compiler is built without RTL
checks.

This patch implements the __jcvt ACLE intrinsic [1] that maps down to the FJCVTZS [2] instruction from Armv8.3-a.
No fancy mode iterators or nothing. Just a single builtin, UNSPEC and define_insn and the associate plumbing.
This patch also defines __ARM_FEATURE_JCVT to indicate when the intrinsic is available.

This test uses a call-saved register as a global variable. It
attempts to preserve its value across main, but only the lower int
part is preserved, which is not good enough for x86_64, when the
runtime that calls main() happens to hold something in the chosen
register that is not a zero-extension from the 32-bit value, and
rightfully expects the full register to remain unchanged when main()
returns.

When compiling glibc we found that the GOT register was being allocated
r9 when the instruction was still set_got_tmp. That is a problem
because r9 is the Link Register (LR) in OpenRISC which is used/clobbered
in set_got. We cannot use r9 as the GOT register. Also, we cannot
simply say set_got_tmp clobbers r9 as this is the reason for having the
temporary set_got_tmp.
Fix by using a register class constraint that does not allow r9 during
register allocation.

* config/or1k/constraints.md (t): New constraint.
* config/or1k/or1k.h (GOT_REGS): New register class.

When generating write barriers, we were only checking for a notinheap
struct at the outermost struct. That mishandled the case of setting a
pointer to a notinheap struct as a field of another struct that is not
notinheap. This caused an invalid write barrier error when building
the 1.13 version of the runtime.
