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

remove a dead APInt ctor.

avoid string thrashing when formatting names in output.  This
speeds up release-asserts llvm-dis on kc++ from 1.86s to 1.04s (~79%)

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54868 91177308-0d34-0410-b5e6-96231b3b80d8

random cleanups.

add support for a cout/cerr analog (outs()/errs()) as well as
a simple adaptor class to give raw output capabilities to
something that wants to write to an ostream.

opening "-" automatically yields stdout.

rename OutputData to 'write' to match ostream.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54857 91177308-0d34-0410-b5e6-96231b3b80d8

remove accidental comment.

add a new raw_ostream class which is an extremely high performance ostream that
can *only* output data (no seeking, reading, etc).  This is adapted from the
clang "-E outputter", and is roughly 10% faster than stdio on darwin and 30%
(or more) faster than std::ostream.

PPC/Linux normally uses named section for bss

Use proper strings section name for PPC

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54846 91177308-0d34-0410-b5e6-96231b3b80d8

Use correct name for TLS address resolution routine on x86-64

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54845 91177308-0d34-0410-b5e6-96231b3b80d8

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.

Reduce heap trashing due to std::string construction / concatenation via caching of section flags string representations

Remove GCSE and LoadVN from the testsuite.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54832 91177308-0d34-0410-b5e6-96231b3b80d8

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

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54822 91177308-0d34-0410-b5e6-96231b3b80d8

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

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54821 91177308-0d34-0410-b5e6-96231b3b80d8

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

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54820 91177308-0d34-0410-b5e6-96231b3b80d8

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

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54819 91177308-0d34-0410-b5e6-96231b3b80d8

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

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54814 91177308-0d34-0410-b5e6-96231b3b80d8

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

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54813 91177308-0d34-0410-b5e6-96231b3b80d8

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