cb8c4778d3 Cleanup. Remove redundant llvm:: , we don't need them since we're inside 
namespace llvm already.

f34be827ac StringMap<DIE*>::iterator::first() returns a pointer to the first character of 
the key. This will cause it to create a new std::string, which isn't
wanted. Instead, pass back the "const char*". Modify the EmitString() method to
take a "const char*".

d9df501704 Fix pr3954. The register scavenger asserts for inline assembly with 
register destinations that are tied to source operands.  The
TargetInstrDescr::findTiedToSrcOperand method silently fails for inline
assembly.  The existing MachineInstr::isRegReDefinedByTwoAddr was very
close to doing what is needed, so this revision makes a few changes to
that method and also renames it to isRegTiedToUseOperand (for consistency
with the very similar isRegTiedToDefOperand and because it handles both
two-address instructions and inline assembly with tied registers).

685cb17c98 Make sure to rebuild dependencies for the check' and unittests' targets so 
we're not testing out-of-date code.  This also makes "make check" and
"make unittests" work out-of-the box right after the configure step, without
requiring the user to run "make tools-only" or "make libs-only".

Tested on Linux/x86_64 and Darwin/x86.

57fc82d409 Generalize ExtendUsesToFormExtLoad to be usable for ANY_EXTEND, 
in addition to ZERO_EXTEND and SIGN_EXTEND. Fix a bug in the
way it checked for live-out values, and simplify the way it
find users by using SDNode::use_iterator's (relatively) new
features. Also, make it slightly more permissive on targets
with free truncates.

In SelectionDAGBuild, avoid creating ANY_EXTEND nodes that are
larger than necessary. If the target's SwitchAmountTy has
enough bits, use it. This exposes the truncate to optimization
early, enabling more optimizations.

8e5c0da848 Don't copy the operand of a SwitchInst into virtual registers as 
eagerly. This helps avoid CopyToReg nodes in some cases where they
aren't needed, and also helps subsequent optimizer heuristics
in cases where the extra nodes would cause the node to appear
to have multiple results. This doesn't have a significant impact
currently; it'll help an upcoming change.

ddfa57bd7b Instcombine should not promote whole computation trees to "strange" 
integer types, unless they are already strange.  This prevents it from
turning the code produced by SROA into crazy libcalls and stuff that 
the code generator can't handle.  In the attached example, the result
was an i96 multiply that caused the x86 backend to assert.

Note that if TargetData had an idea of what the legal types are for
a target that this could be used to stop instcombine from introducing
i64 muls, as Scott wanted.
