Dan Gohman 4f9c40c521 Change the logic which interprets output on stderr as an error so that
it doesn't modify the exit code or the stdout contents, and so that it
doesn't clutter the output with "Command has output on stderr!".

Dan Gohman 794172ca9c Don't print "Command output (stdout):" when the command has no output,
and same for stderr, to avoid clutter in the output.

Daniel Dunbar a19db3594f tests: Add an 'llvm-lit' tool (script), which gets generated as part of the
build and has the object build directory baked into it. This allows 'llvm-lit'
to properly find the information needed to run the test suite in all cases,
without requiring the user to have LLVM or 'lit' available in their PATH, for
example.

Bill Wendling 9b8d586039 Add a "Compare" flag to the target instruction descriptor. This will be used
later to identify and possibly remove superfluous compare instructions -- those
that are testing for and setting a status flag that should already be set.

Jim Grosbach d343166a0b Many Thumb2 instructions can reference the full ARM register set (i.e.,
have 4 bits per register in the operand encoding), but have undefined
behavior when the operand value is 13 or 15 (SP and PC, respectively).
The trivial coalescer in linear scan sometimes will merge a copy from
SP into a subsequent instruction which uses the copy, and if that
instruction cannot legally reference SP, we get bad code such as:
  mls r0,r9,r0,sp
instead of:
  mov r2, sp
  mls r0, r9, r0, r2

This patch adds a new register class for use by Thumb2 that excludes
the problematic registers (SP and PC) and is used instead of GPR
for those operands which cannot legally reference PC or SP. The
trivial coalescer explicitly requires that the register class
of the destination for the COPY instruction contain the source
register for the COPY to be considered for coalescing. This prevents
errant instructions like that above.

   fail to end up the top of the entry block.

Bruno Cardoso Lopes 792e906bef Start the support for AVX instructions with 256-bit %ymm registers. A couple of
notes:
- The instructions are being added with dummy placeholder patterns using some 256
  specifiers, this is not meant to work now, but since there are some multiclasses
  generic enough to accept them,  when we go for codegen, the stuff will be already
  there.
- Add VEX encoding bits to support YMM
- Add MOVUPS and MOVAPS in the first round
- Use "Y" as suffix for those Instructions: MOVUPSYrr, ...
- All AVX instructions in X86InstrSSE.td will move soon to a new X86InstrAVX
  file.

Duncan Sands 408bb192de Rename "Release" builds as "Release+Asserts"; rename "Release-Asserts"
builds to "Release".  The default build is unchanged (optimization on,
assertions on), however it is now called Release+Asserts.  The intent
is that future LLVM releases released via llvm.org will be Release builds
in the new sense, i.e. will have assertions disabled (currently they have
assertions enabled, for a more than 20% slowdown).  This will bring them
in line with MacOS releases, which ship with assertions disabled.  It also
means that "Release" now means the same things in make and cmake builds:
cmake already disables assertions for "Release" builds AFAICS.
