	* tree-vrp.c (extract_range_from_multiplicative_op): Add
	type parameter and use it instead of guessing expression
	type from the first operand.
	(extract_range_from_binary_expr): Pass expr_type down.

GCC 10 now supports having RTL codes being code attributes (thanks
Richard) allowing us to map smax to smin and vice versa.
This means we can clean up their use in the saturation patterns that do
the cross product of [smin, smax] and use the pattern
predicate to cancel out the nonsense ones.

	* config/arm/arm.md (SATrev): Change to code attribute.
	(*satsi_<SAT:code>): Adjust for the above.
	(*satsi_<SAT:code>_shift): Likewise.

When entering an interrupt, not only the call save registers needs to
be place on stack but also the call clobbers one. More over, the
ARC700 return from interrupt instruction needs to be rtie, the same
like ARCv2 CPUs. While the ARC6xx family uses j.f [ilinkX]
instruction. Additionally, we need to save the state of the ZOL
machinery, namely the lp_count, lp_end and lp_start registers. For
architectures which are using extension registers (i.e., HS48) we need
to save/restore them as well.

From-SVN: r273747

This is about 32/64b host and multilib support across the range of Darwin
systems.

Prior to Darwin8 (OS X 10.4), the toolchains support only PowerPC and only 32b.

On Darwin8 it is possible to target a 64b multilib, but with support limited
to a few of the main libraries on the system (not a recommended configuration).

From Darwin9 to Darwin17 (OSX 10.5 to 10.13) it is possible to have either
32 or 64b hosted toolchains, with support for a 64 or 32b multilib respectively.

On Darwin9 the kernel is 32b, but with support for 64b executables, so it's
conventional to build a 32b host toolchain supporting a 64b multilib.  However
this is not enforced (merely a convention).

There is also some platform hardware supporting Darwin10/11 which is only 32b
and for which the same situation applies.  However, from Darwin10 to Darwin17,
the majority of platform hardware supports a 64b kernel and it's conventional
to build a 64b host toolchain with support for a 32b multilib.

On/from Darwin18 (OS X 10.14), the development headers (in the SDK) no longer
expose the interfaces for the 32b multilib support (although sufficient runtime
support remains installed that the testsuite can be run for a 32b multilib).

The PR is raised against this latter situation since the absence of exposed
interfaces causes a 'default' bootstrap fail regardless of the availability of
the runtimes.  Given the number of permutations, I felt it warranted a general
solution, especially since the current scheme of target headers and t-make
fragments has become somewhat messy.

The changes here enforce the single 32b PowerPC multilib for Darwin < 8 and the
single X86 64b multilib for Darwin >= 18.  This means that there is no longer
any need to configure Darwin18+ '--disable-multilib', but also that if you want
to use the ability to continue to test the compiler's 32b multilib there, you
need to make a configuration targeting an earlier OS version (and using the
SDK from that).
