Darwin, Driver - Improve processing of macosx-version-min=
For PR target/63810 some improvements were made in the parsing of
the version string at the point it's used to define the built-in
__ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__. This is fine, but the
specs processing also uses the version, and specs version-compare
doesn't like leading zeros on components. This means that while we
succeed in processing -mmacosx-version-min=010.00002.000099 on compile
lines, it fails for any other line that uses the value as part of a spec
(in particular, link lines fail).
To fix this, we need to apply a bit of clean-up to the version that's
presented to the driver, and push that back into the command line opts.
The value can come from four places:
1. User-entered on the command line
2. User-entered as MACOSX_DEPLOYMENT_TARGET= environment var.
3. Absent those two
3a For self-hosting systems, look-up from the kernel
3b For cross-compilers, as a default supplied at configure time.
We apply the clean-up to all 4 (although it shouldn't really be needed
for the cases under 3).
We also supply a test-case that adapts to the target-version of the
system, so that the link requirements are met by the SDK in use (if you
try to link i686-darwin9 on an x86-64-darwin18 SDK, it will fail).

Replace std::to_string for integers with optimized version
The std::to_chars functions from C++17 can be used to implement
std::to_string with much better performance than calling snprintf. Only
the __detail::__to_chars_len and __detail::__to_chars_10 functions are
needed for to_string, because it always outputs base 10 representations.
The return type of __detail::__to_chars_10 should not be declared before
C++17, so the function body is extracted into a new function that can be
reused by to_string and __detail::__to_chars_10.
The existing tests for to_chars rely on to_string to check for correct
answers. Now that they use the same code that doesn't actually ensure
correctness, so add new tests for std::to_string that compare against
printf output.

The midend expects the optab to compute the absolute differences of operands 1

are V16QImode and the output is V4SImode.

compiler: make heap expression's write barrier conditional
Heap_expression::do_get_backend emits an unconditional write
barrier if the type has pointers and it is not a stack allocation.
This CL changes it to use a write barrier for the assignment only
when write barriers are enabled. While here, also change it to
call gcWriteBarrier instead of typedmemmove for pointer-shaped
types.
For this to work, Function::build needs to be adjusted so that
Heap_expression::do_get_backend is called when there is a parent
block.
