6bf068351e Fix some scavenger performance issues. 
- Don't call malloc+free in the very hot forward().
- Don't call isTiedToDefOperand().
- Don't create BitVector temporaries.
- Merge DeadRegs into KillRegs.
- Eliminate the early clobber checks, they were irrelevant to scavenging.
- Remove unnecessary code from -Asserts builds.

This speeds up ARM PEI by 3.4x and overall llc -O0 codegen time by 11%.

033045b6da Add a BitVector::reset(BitVector&) method. 
The alternative LHS &= ~RHS is way too slow because it creates a
temporary that calls malloc/free.

16ac64c902 Don't always create a separate block for the call to _Unwind_Resume. 
Sometimes there is only one 'resume' instruction per function. In those
situations, we don't need a separate block for the call to _Unwind_Resume. In
fact, it adds a lot of overhead to code-gen if we do that -- especially at -O0.
If we have a single 'resume' instruction, just generate the call within that
block.

de918de31c Remove Deprecated Features 
Move to a model where we build whatever branches are checked out
in the source directories.  This was a bit too smart (and complicated)
in handling details best left to the user and the revision control
system.

In addition, get rid of support for llvm-gcc and building gcc as
these are no longer necessary.

e0f0352889 Add a "moveInstr" method to LiveIntervals. This can be used to move instructions 
around within a basic block while maintaining live-intervals.

when reordering MIs.

as ConstantVector.

8ac1e67396 Place the GEP instructions nearer to the instructions which use them. 
GEP instructions are there for the compiler and shouldn't really output much
code (if any at all). When a GEP is stored in the entry block, Fast ISel (for
one) will not know that it could fold it into further uses. For instance, inside
of the EH handling code. This results in a lot of unnecessary spills and loads
which bloat code and slows down pretty much everything.

67b57ec4e3 Rewrite CanShareConstantPoolEntry to be implemented in terms of the 
mid-level constant folding APIs instead of doing its own analysis.
This makes it more general (e.g. can now share a <2 x i64> with a
<4 x i32>) and avoid duplicating a bunch of logic.
