Fix clients like this:

  llvm_shutdown();
  delete ParseBytecodeFile(InputFilename, 0, &ErrorMessage);

The primitive type objects failed to ressurect themselves after shutdown, leading
to crashes in clients that used them after llvm_shutdown().

This solution isn't wonderful, because we clearly have static ctors.  However,
the code it replaces was just as bad, so it's not a regression.

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.

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.

Added new method to finish up the addition of passes to emit files. This
allows us to split that method into two so that we can optionally call a
concrete function to add a writer. Removed moribund addObjectWriter()
method.

Dead files. Functionality has been taken over by the Add*Writer functions.

For PR1187:
When a naming conflict arises, allow internal linkage functions to be
renamed without warning or error.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34024 91177308-0d34-0410-b5e6-96231b3b80d8

For PR1187:
Allow @ before identifer names. Recognize the i1, i8, i16, i32, i64 keywords
as type names corresponding to bool, ubyte, ushort, uint, and ulong
respectively. While these aren't LLVM 1.9 constructs, permitting the syntax
allows post-1.9 assembly files to be upgraded.

move archive-specific stuff out of bcreader into archive library.

move an llvmc-specific function out of the bcreader into llvmc.

move AnalyzeBytecodeFile out of ReaderWrappers.cpp into Analyzer.cpp.  Now
lli doesn't link in Analyzer.cpp.

For PR1187:
Add a test to ensure that i1, i8, i16, i32 and i64 are recognized by the
lexer and vars using them will be renamed appropriately.

For PR1187:
Add a test case to test rename of internal linkage functions with the same
name, without an error or warning.

new testcase for nested functions

This really only affects pointers in high memory, and only llvm 1.9, but make a regression for it anyway

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34014 91177308-0d34-0410-b5e6-96231b3b80d8

isLowRegister() expects input is a physical register.

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.

Automatically generating intrinsic declarations from Dan Gohman.  Modified

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!
