Fix low reg issue in Thumb-2 movsi patterns
The Thumb-2 movsi patterns try to prefer low registers for loads and stores.
However this is done incorrectly by using 2 separate variants with 'l' and 'h'
register classes. The register allocator will only use low registers, and
as a result we end up with significantly more spills and moves to high
registers. Fix this by merging the alternatives and use 'l*r' to indicate
preference for low registers. This saves ~400 instructions from the pr77308
testcase.

[arm][committed] Clean up code iterator usage in satsi* patterns
GCC 10 now supports having RTL codes being code attributes (thanks

[Darwin] Fix PR87030 and tidy config fragments.
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).

[Ada] Plug small loophole in Generate_Range_Check
The Generate_Range_Check routine is responsible for generating range
checks in the scalar case. It automatically deals with possible
overflow in the process when the source and the target base types are
different.
However there is one case where overflow is not dealt with correctly,
namely when the target base type is narrower than the source base type
and both are floating-point types. In this case, the routine will
convert the source type to the target base type without checking for
overflow. In practice this does not matter much because the conversion
would yield an infinity on overflow, which would then fail the
subsequent range check. However it's more correct to have a proper
overflow check with -gnateF than relying on the infinity.

compiler: follow-on fix for finalizing imported methods
This patch is a revision to CL 185518, which added code to perform
finalization of methods on types created by the importer and not
directly reachable until inlining is done.
The original fix invoked the finalization code at the end of
Import::read_types(), but it turns out this doesn't handle the case
where a type with methods is read in due to a reference from something
later in the export data (a function or variable). The fix is to move
the import finalization call to the end of Import::import().
Testcase for this bug is in CL 187057.
