Set trunc store action to Expand for all X86 targets.
When compiling without SSE2, isTruncStoreLegal(F64, F32) would return
Legal, whereas with SSE2 it would return Expand. And since the Target
doesn't seem to actually handle a truncstore for double -> float, it
would just output a store of a full double in the space for a float
hence overwriting other bits on the stack.

This should fix clang -O0 on i386 assigning garbage to floats, in
certain scenarios.

many thanks for their continued support of FreeBSD.
While I'm there, also implement a new build knob, WITHOUT_HYPERV to
disable building and installing of the HyperV utilities when necessary.
The HyperV utilities are only built for i386 and amd64 targets.
This is a stable/10 candidate for inclusion with 10.1-RELEASE.

MFV: Only emit movw on ARMv6T2
Building for the FreeBSD default target ARMv6 was emitting movw ASM on certain
test cases (found building qmake4/5 for ARM). Don't do that, moreover, the AS
in base doesn't understand this instruction for this target. One would need
to use --integrated-as to get this to build if desired.

libraries that need to be linked into an executable or library have to be
listed on the command line explicitly. This commit fixes a bug in ld(1)
where it would scan dependencies of the libraries on the command line and
link them if needed if they were also found in ld.so.cache.
The important bit of the patch is the initialisation of needed.by such that
libraries found by scanning dependencies are marked as such and not used in
the link.
The patch is a backport of binutils git commit

1) " ext" length should be included into OPIE_CHALLENGE_MAX (as all places
of opie code expects that).
2) Overflow check in challenge.c is off by 1 even with corrected
OPIE_CHALLENGE_MAX
3) When fallback to randomchallenge() happens and rval is 0 (i.e.
challenge is too long), its value should be set to error state too.
To demonstrate the bug, run opiepasswd with valid seed:
opiepasswd -s 1234567890123456
and notice that it falls back to randomchallenge() (i.e. no
1234567890123456 in the prompt).

the same values as the -march= command line option. Add support for the
"sec" extension (security extensions).
We've been getting away without support for the sec extension because
it's bogusly enabled even on arches where its presence is optional. This
support for .arch_extension is being added mainly so that we can use the
right directives in our source code, and that helps folks using external
toolchains (and will help us when we finally update our toolchain).

This is a partial fix for reverse lookups in RFC 1918 networks. With

it will still reject the answer it gets from the forwarder, because

[PPC64] Fix PR20071 (fctiduz generated for targets lacking that
instruction)
PR20071 identifies a problem in PowerPC's fast-isel implementation
for floating-point conversion to integer. The fctiduz instruction
was added in Power ISA 2.06 (i.e., Power7 and later). However, this
instruction is being generated regardless of which 64-bit PowerPC
target is selected.
The intent is for fast-isel to punt to DAG selection when this
instruction is not available. This patch implements that change.
For testing purposes, the existing fast-isel-conversion.ll test adds
a RUN line for -mcpu=970 and tests for the expected code generation.
Additionally, the existing test fast-isel-conversion-p5.ll was found
to be incorrectly expecting the unavailable instruction to be
generated. I've removed these test variants since we have adequate
coverage in fast-isel-conversion.ll.
This is needed to compile clang with debug+asserts on older powerpc64
and ppc970 targets.
