My compiler complains that "x always evaluates to true"
in this call:

Result.IntVal = APInt(80, 2, x);

What is x?

uint16_t x[8];

I deduce that the APInt constructor being used is this one:

  APInt(uint32_t numBits, uint64_t val, bool isSigned = false);

rather than this one:

  APInt(uint32_t numBits, uint32_t numWords, const uint64_t bigVal[]);

That doesn't seem right!  This fix compiles but is otherwise completely

Updated GenLibDeps.pl to employ "use strict" to help prevent uses of variables
that have not yet been defined.

Removed used of grep and sed when parsing the results of "nm". This was
originally motivated because if the user has specified options to grep using
the environment variable GREP_OPTIONS this could break the script. Piping
through grep/sed/sort/uniq is also (to my understanding) not necessary, and
the equivalent operations can be done much faster in the Perl script.

Using a crude benchmark, these changes resulted in a 3x speedup in the
execution of GenLibDeps.pl.

This patch fixes this by always arranging for zero/one vectors
to be defined as v4i32 or v2i32 (SSE/MMX) instead of letting them be
any random type.  This ensures they get trivially CSE'd on the dag.
This fix is also important for LegalizeDAGTypes, as it gets unhappy
when the x86 backend wants BUILD_VECTOR(i64 0) to be legal even when
'i64' isn't legal.

This patch makes the following changes:

1) X86TargetLowering::LowerBUILD_VECTOR now lowers 0/1 vectors into
   their canonical types.
2) The now-dead patterns are removed from the SSE/MMX .td files.
3) All the patterns in the .td file that referred to immAllOnesV or
   immAllZerosV in the wrong form now use *_bc to match them with a
   bitcast wrapped around them.
4) X86DAGToDAGISel::SelectScalarSSELoad is generalized to handle
   bitcast'd zero vectors, which simplifies the code actually.
5) getShuffleVectorZeroOrUndef is updated to generate a shuffle that
   is legal, instead of generating one that is illegal and expecting
   a later legalize pass to clean it up.
6) isZeroShuffle is generalized to handle bitcast of zeros.
7) several other minor tweaks.

This patch is definite goodness, but has the potential to cause random
code quality regressions.  Please be on the lookout for these and let
me know if they happen.

Unbreak Duncan's carefully written path compression where I didn't realize

Several changes:
1) Change the interface to TargetLowering::ExpandOperationResult to
   take and return entire NODES that need a result expanded, not just
   the value.  This allows us to handle things like READCYCLECOUNTER,
   which returns two values.
2) Implement (extremely limited) support in LegalizeDAG::ExpandOp for MERGE_VALUES.
3) Reimplement custom lowering in LegalizeDAGTypes in terms of the new
   ExpandOperationResult.  This makes the result simpler and fully
   general.
4) Implement (fully general) expand support for MERGE_VALUES in LegalizeDAGTypes.
5) Implement ExpandOperationResult support for ARM f64->i64 bitconvert and ARM
   i64 shifts, allowing them to work with LegalizeDAGTypes.
6) Implement ExpandOperationResult support for X86 READCYCLECOUNTER and FP_TO_SINT,
   allowing them to work with LegalizeDAGTypes.

LegalizeDAGTypes now passes several more X86 codegen tests when enabled and when
type legalization in LegalizeDAG is ifdef'd out.

Ding dong, the DoesntAccessMemoryFns and
