--force-configure to force running configure before building.
--extra-llvm-config-flags
--extra-llvm-gcc-config-flags
--extra-gcc-config-flags
Pass additional argument to the various configure invocations.
This also eliminates a default build flavor because explicitly
specifying builds could result in build flavors being run repeatedly.
Finally, turn off fortran builds for the moment because install
appears to be broken.

Yes, there are other types than i8* and GEPs on them can produce an add+multiply.
We don't consider that cheap enough to be speculatively executed.

is possible to do better if the high bit is set in either KnownZero/KnownOne, but
in practice NumSignBits is always 1 when we are zero extending because nothing
is known about that register.

D registers since the vpush list may not have gaps. Make sure the stack
adjustment instruction isn't moved between them. Ditto for vpop in
epilogues.
Sorry, can't reduce a small test case.

New live ranges are assigned in long -> short order, but live ranges that have
been evicted at least once are deferred and assigned in short -> long order.
Also disable splitting and spilling for live ranges seen for the first time.
The intention is to create a realistic interference pattern from the heavy live
ranges before starting splitting and spilling around it.

Introduce a variable in the AsmParserExtension whether [] is valid in an
expression. If it is true, parse them like (). Enable this for ELF only.

Limit the folding of any_ext and sext into the load operation to scalars.
Limit the active-bits trunc optimization to scalars.
Document vector trunc and vector sext in LangRef.
Similar to commit 126080 (for enabling zext).

The problem was codegen guessing the wrong values and printing
.section .eh_frame,"aMS",@progbits,4
It is not clear at all if Codegen should try to guess, MC is the
one that should know the default flags.

Some tests on Windows use the "not" utility and fail with an error "program not executable". The reason for this error is that the name of the executable file sended to the "not" without the extension.

registers at phis. This enables us to eliminate a lot of pointless zexts during
the DAGCombine phase. This fixes <rdar://problem/8760114>.

function prototype into a call to a varargs prototype. We do
allow the xform if we have a definition, but otherwise we don't
want to risk that we're changing the abi in a subtle way. On
X86-64, for example, varargs require passing stuff in %al.

enabled for all targets. Non-X86 targets should not have this behavior
enabled by default.
Joerg, if you would like to resubmit with the behavior conditionalized to be
X86-ELF only, that's fine.
