For PR1153:
Make llvm-ld more gccld-like by having it run the same set of passes. The

reason to have only one optimizing linker in in LLVM.

add some signed/unsigned arithmetic operation functions into APInt.h to

namespace "APIntOps" which is inside llvm namespace.

For PR1187:
Always rename, never give a redef error. We could check for collapsed type
planes and generate an error if that's not the cause, but the 99.9999
percentile case will be that its the result of collapsed type planes. So,
rather than doing an expensive check, just rename.

For PR1187:
Some changes to get the smbd.ll test case working:
1. Move the logic for CSRETCC->sret attribute out of the ResolveDefinitions
   code and into getExistingValue. This resolves it much earlier and works
   in function scope as well.
2. Fix handling of CSRETCC->sret for the store instruction.
3. Rewrite the code for handling renaming to factor in linkage types.
4. Rename a structure filed for a PATypeInfo* so it doesn't get confused
   with a field for a Type*.

Fixed a long standing spiller bug that's exposed by Thumb:

The code sequence before the spiller is something like:
                 = tMOVrr
        %reg1117 = tMOVrr
        %reg1078 = tLSLri %reg1117, 2

The it starts spilling:
        %r0 = tRestore <fi#5>, 0
        %r1 = tRestore <fi#7>, 0
        %r1 = tMOVrr %r1<kill>
        tSpill %r1, <fi#5>, 0
        %reg1078 = tLSLri %reg1117, 2

It restores the value while processing the first tMOVrr. At this point, the
spiller remembers fi#5 is available in %r0. Next it processes the second move.
It restores the source before the move and spills the result afterwards. The
move becomes a noop and is deleted. However, a spill has been inserted and that
should invalidate reuse of %r0 for fi#5 and add reuse of %r1 for fi#5.
Therefore, %reg1117 (which is also assigned fi#5) should get %r1, not %r0.

The new version of how to add passes to emit files. We explicitly call a

Moved the MachOWriter and ELFWriter out of the Target/* files. Placed the

Split the addPassesToEmitFile method up into two. This is so that we can

a concrete function), and then do some finishing stuff, if need be.

Added new method to finish up the addition of passes to emit files. This

method.

push bytecode decompressor out through APIs.  Now the bytecode reader
api's look like this:

ModuleProvider *getBytecodeModuleProvider(
  const std::string &Filename,  ///< Name of file to be read
  BCDecompressor_t *BCDC = Compressor::decompressToNewBuffer,
  std::string* ErrMsg = 0,      ///< Optional error message holder
  BytecodeHandler* H = 0        ///< Optional handler for reader events
);

This is ugly, but allows a client to say:

  getBytecodeModuleProvider("foo", 0);

If they do this, there is no dependency on the compression libraries, saving
codesize.

Fix Transforms/DeadArgElim/2007-02-07-FuncRename.ll, fallout from PR411.
This happened because deadargelim now causes VMCore to auto-rename every
function that it hacks arguments out of.  Because it hacks arguments out of
functions in a non-deterministic order, this caused the resultant numbering
to be nondet.  The fix is to just be careful to not rename functions!

eliminate ValueSymbolTable::rename, it has no advantage over using remove+insert.

Fix a fixme by correctly calculating preferred alignments for functions,
based on the alignment of the symbol and the target data's preferred align
for that type.

Also, rename some arguments for consistency.

Eliminate the O(n) version of TypeSymbolTable::remove, it is dead.  When
inserting a type into the type symbol table, only compute unique name if not
in symtab already.

Eliminate a bunch of work from ValueSymbolTable::insert for the common case
where a symbol name doesn't conflict.  This speeds up bc reading 16% on 176.gcc!

redesign the primary datastructure used by mem2reg to eliminate an
std::map of std::vector's (ouch!).  This speeds up mem2reg by 10% on 176.gcc.

Fix a really subtle bug where the entire hash table could fill with
tombstones, causing subsequent insertions to infinitely loop.

Two fixes:
1. Memset takes an i32 for the value to set, not i8.  This was causing GCC to
   ICE all over the place (PR1183).
2. memcpy/memmove were not properly zext/trunc'ing the size in some cases.

Implement the NO_INSTALL feature. Setting this variable to any value in
a directory's Makefile will prevent the build products from that directory
from being installed. This is useful for tools and libraries that are
only useful as part of the build process.
