Rename some GC classes so that their roll will hopefully be clearer.

In particular, Collector was confusing to implementors. Several
thought that this compile-time class was the place to implement
their runtime GC heap. Of course, it doesn't even exist at runtime.
Specifically, the renames are:

  Collector               -> GCStrategy
  CollectorMetadata       -> GCFunctionInfo
  CollectorModuleMetadata -> GCModuleInfo
  CollectorRegistry       -> GCRegistry
  Function::getCollector  -> getGC (setGC, hasGC, clearGC)

Several accessors and nested types have also been renamed to be
consistent. These changes should be obvious.

avoid an extraneous std::string construction

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54875 91177308-0d34-0410-b5e6-96231b3b80d8

Rework the routines that convert AP[S]Int into a string.  Now, instead of
returning an std::string by value, it fills in a SmallString/SmallVector
passed in.  This significantly reduces string thrashing in some cases.

More specifically, this:
 - Adds an operator<< and a print method for APInt that allows you to
   directly send them to an ostream.
 - Reimplements APInt::toString to be much simpler and more efficient
   algorithmically in addition to not thrashing strings quite as much.

This speeds up llvm-dis on kc++ by 7%, and may also slightly speed up the
asmprinter.  This also fixes a bug I introduced into the asmwriter in a

Add interface for section override. Use this for Sparc, since it should use named BSS section.

Move SLEB/ULEB size calculation routines from AsmPrinter to TargetAsmInfo. This makes JIT asmprinter-free.

Remove GCSE, ValueNumbering, and LoadValueNumbering.  These have been deprecated for almost a year; it's finally time for them to go away.

Reapply 54786. Add overflow and number of mantissa bits checks.

Convert several std::vectors over to SmallVector, and use reserve() as appropriate for cases where std::vector is still used.

Add a value_type typedef to SmallVector, to make it more compatible with STL adapters.

Inline the fastpath of PATypeHolder::get().  This is a small speedup in
instcombine among other things.

Revert 54786. It's not checking for overflows, etc.

use smallvector instead of vector for a couple worklists.  This speeds up instcombine
by ~10% on some testcases.

The pass manager is not able to schedule -loop-deletion -loop-index-split.

The loop-deletion pass does not preserve dom frontier, which is required by
loop-index-split. When the PM checks dom frontier for loop-index-split, it has
already verified that lcssa is availalble. However, new dom frontier forces new
loop pass manager, which does not  have lcssa yet.

The PM should recheck availability of required analysis passes in such cases.

Convert uses of std::vector in TargetInstrInfo to SmallVector.  This change had to be propoagated down into all the targets and up into all clients of this API.

Don't try to use the insertps instruction for vector
element inserts with non-constant indices. This fixes
