(almost) a register copy. However, it always coalesced to the register of the
RHS (the super-register). All uses of the result of a EXTRACT_SUBREG are sub-
register uses which adds subtle complications to load folding, spiller rewrite,
etc.

Fix DecomposeSimpleLinearExpr to handle simple constants better.
Don't nuke gep(bitcast(allocation)) if the bitcast(allocation) will
fold the allocation.  This fixes PR1728 and Instcombine/malloc3.ll

the extra bits are all zeros.  This allows  "010" and "010000" to be
treated as equal.

may be overloaded with vector types. And add a testcase for codegen for
these.

Factor out the code that expands the "nasty scalar code" for unrolling
vectors into a separate routine, teach it how to handle mixed
vector/scalar operands, as seen in powi, and use it for several operators,
including sin, cos, powi, and pow.

Add support in SplitVectorOp for fpow, fpowi and for several unary
operators.

performed if the following conditions are satisfied:

  elf/pic enabled + callee is in module + callee has

No compile-time support for constant operations yet,
just format transformations.  Make readers and

Legalize.
