Paul Floyd 3e7774ea5a Bug 452274 memcheck crashes with Assertion 'sci->status.what == SsIdle' failed 
FreeBSD (and Darwin) use the carry flag for syscall syscall status.
That means that in the assembler for do_syscall_for_client_WRK
they have a call to LibVEX_GuestAMD64_put_rflag_c (amd64) or
LibVEX_GuestX86_put_eflag_c (x86). These also call WRK functions.

The problem is that do_syscall_for_client_WRK has carefully crafted
labels correspinding to IP addresses. If a signal interrupts
processdings, IP can be compared to these addresses so that
VG_(fixup_guest_state_after_syscall_interrupted) can work
out how to resume the syscall. But if IP is in the save
carry flag functions, the address is not recognized and
VG_(fixup_guest_state_after_syscall_interrupted) fails.

The crash in the title happens because the interrupted
syscall does not reset its status, and on the next syscall
it is expected that the status be idle.

To fix this I added global variables that get set to 1
just before calling the save carry flag functions, and cleared
just after. VG_(fixup_guest_state_after_syscall_interrupted)
can then check this and work out which section we are in
and resume the syscall correctly.

Also:

Start a new NEWS section for 3.20

Add a regtest for this and also a similar one for Bug 445032
(x86-freebsd only, new subdir).

I saw that this problem also probably exists with macOS, so I made
the same changes there (not yet tested)

# Platform variants?
#----------------------------------------------------------------------------
# Normally the PLAT = (ARCH, OS) characterisation of the platform is enough.
# But there are times where we need a bit more control. The motivating
# and currently only case is Android: this is almost identical to
# {x86,arm,mips}-linux, but not quite. So this introduces the concept of
# platform variant tags, which get passed in the compile as
# -DVGPV_<arch>_<os>_<variant> along with the main -DVGP_<arch>_<os> definition.
#
# In almost all cases, the <variant> bit is "vanilla". But for Android
# it is "android" instead.
#
# Consequently (eg), plain arm-linux would build with
#
# -DVGP_arm_linux -DVGPV_arm_linux_vanilla
#
# whilst an Android build would have
#
# -DVGP_arm_linux -DVGPV_arm_linux_android
#
# Same for x86. The setup of the platform variant is pushed relatively far
# down this file in order that we can inspect any of the variables set above.
# In the normal case ..

# There now follow some tests for Boost, and OpenMP. These

# these packages. All regression test programs all compiled only
# for the primary target. And so it is important that the configure
# checks that follow, use the correct -m32 or -m64 flag for the
# primary target (called $mflag_primary). Otherwise, we can end up
# in a situation (eg) where, on amd64-linux, the test for Boost checks
# for usable 64-bit Boost facilities, but because we are doing a 32-bit
# only build (meaning, the primary target is x86-linux), the build
# of the regtest programs that use Boost fails, because they are
# build as 32-bit (IN THIS EXAMPLE).
#
# Hence: ALWAYS USE $mflag_primary FOR CONFIGURE TESTS FOR FACILITIES
# NEEDED BY THE REGRESSION TEST PROGRAMS.
