969028053f Handle Octeon 3 not supporting MIPS paired-single instructions.
The Octeon 3 processor does not support the MIPS paired-single
instructions.  This results in illegal instruction errors in the
testsuite when vectorization tests try to use those instructions.

This patch teaches the compiler about that lack of support, so that
warnings are given when -mpaired-single (or something implying it) is
used when compiling for such a processor.  I chose to test
TARGET_OCTEON as the simplest conditional; since the older Octeon
processors don't support hard float at all, I don't think the choice
matters for them.  Tests that then failed with the warning were
updated to disable them for Octeon.

Tested with no regressions for cross to mips64el-linux-gnu (Octeon
3).

	* config/mips/mips.h (ISA_HAS_PAIRED_SINGLE): Require
	!TARGET_OCTEON.

677cb11df0 Optimise hash_table::empty
Calling redirect_edge_var_map_empty after each pass was slowing things
down because hash_table::empty () cleared all slots even if the hash
table was already empty.

Tested on x86_64-linux-gnu, where it gives a 1% compile time improvement
for fold-const.ii at -O and -O2.

gcc/
	* hash-table.h (hash_table::empty): Turn into an inline wrapper
	that checks whether the table is already empty.  Rename the
	original implementation to...
	(hash_table::empty_slot): ...this new private function.
