Attributor: Avoid double map lookup in updateAttrMap
This will leave behind the map entry in the unchanged case,
but this seems to not matter. Could erase the newly inserted
entry if that happens, but that also doesn't seem to make a
difference.
Enable the standard set of USB devices from usbdevices.config in
macppc/conf/POWERMAC_G5, like they are in macppc/conf/GENERIC.

[RISCV] Fold shladd into Xqcisls scaled load/store in RISCVMergeBaseOffset (#182221)
We can fold `shxadd\qc.shladd` into base+offset load/store instructions
by transforming the load/store into `Xqcisls` scaled load/store
instructions.
For eg.
```
qc.e.li vreg1, s
shxadd vreg2, vreg3, vreg1
lx vreg4, imm(vreg2)
can be transformed to
qc.e.li vreg1, s+imm
qc.lrx vreg4, vreg1, vreg3, (1-7)
```

Due to this, restart the iteration over the p_reapsiblings if the lock
was dropped.

procctl(PROC_REAP_KILL): align error reporting with pgkill(2)
ESRCH from cr_cansignal() means that the target process should be not
visible to the initiator. So do not report pids with ESRCH result.
