FP emulation optimizations. Note that we can measure both directly the impact

glibc >= 2.25 defines canonicalize in commit eaf5ad0
(Add canonicalize, canonicalizef, canonicalizel., 2016-10-26).
Given that we'll be including soon, prepare
for this by prefixing our canonicalize() with sf_ to avoid
clashing with the libc's canonicalize().

The Linux kernel traps certain reserved instruction exceptions to
emulate the corresponding instructions. QEMU is the kernel in user
mode, so those traps are emulated by accepting the instructions.
This change adds the function check_insn_opc_user_only to signal a
reserved instruction exception
This kind of ELF for the R5900 relies on an IEEE 754-1985 compliant FPU.
The R5900 FPU hardware is noncompliant and it is therefore emulated in
software by the Linux kernel. QEMU emulates a compliant FPU accordingly.

The primary purpose of this change is to support programs compiled by
GCC for the R5900 target and thereby run R5900 Linux distributions, for
example Gentoo.

The three-operand MULT and MULTU are the only R5900 specific
instructions emitted by GCC 7.3. The R5900 also implements the three-
operand MADD and MADDU instructions, but they are omitted in QEMU for
now since they are absent in programs compiled by current GCC versions.
Likewise, the R5900
The R5900 implements the 64-bit MIPS III instruction set except DMULT,
DMULTU, DDIV, DDIVU, LL, SC, LLD and SCD. The MIPS IV instructions MOVN,
MOVZ and PREF are implemented. It has the R5900 specific three-operand
instructions MADD, MADDU, MULT and MULTU as well as pipeline 1 versions

If a command fails with a sense that scsi_sense_buf_to_errno converts to
ECANCELED/EAGAIN/ENOTCONN or with a unit attention, scsi_req_complete is
called twice. This caused a crash.

rerror=ignore was returning true from scsi_handle_rw_error but the callers were
not
calling scsi_req_complete when rerror=ignore returns true (this is the correct
thing
to do when true is returned after executing a passthrough command). Fix this by
calling it in scsi_handle_rw_error.
