fa995d7cc5 Factor code to copy global value attributes like 
the section or the visibility from one global
value to another: copyAttributesFrom.  This is
particularly useful for duplicating functions:
previously this was done by explicitly copying
each attribute in turn at each place where a
new function was created out of an old one, with
the result that obscure attributes were regularly
forgotten (like the collector or the section).
Hopefully now everything is uniform and nothing
is forgotten.

768b6f281e Add CommonLinkage; currently tentative definitions 
are represented as "weak", but there are subtle differences
in some cases on Darwin, so we need both.  The intent
is that "common" will behave identically to "weak" unless
somebody changes their target to do something else.

3602011bec Fix PR1146: parameter attributes are longer part of 
the function type, instead they belong to functions
and function calls.  This is an updated and slightly
corrected version of Reid Spencer's original patch.
The only known problem is that auto-upgrading of
bitcode files doesn't seem to work properly (see
test/Bitcode/AutoUpgradeIntrinsics.ll).  Hopefully
a bitcode guru (who might that be? :) ) will fix it.

056b656f99 Improve error handling in the linker by: 
1. Eliminate redundant error messages. LinkInFile and LinkInArchive
   already call the error() method in each case so there's no use
   telling the user again that an item couldn't be linked in.

2. Improve the formatting of error messages (separating content).

3. Change the wording for the warning about unrecognized files. Make
   it clear that the file is being ignored.

43d0b955a3 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.

373d2bccea For PR1064: 
Implement the arbitrary bit-width integer feature. The feature allows
integers of any bitwidth (up to 64) to be defined instead of just 1, 8,
16, 32, and 64 bit integers.

This change does several things:
1. Introduces a new Derived Type, IntegerType, to represent the number of
   bits in an integer. The Type classes SubclassData field is used to
   store the number of bits. This allows 2^23 bits in an integer type.
2. Removes the five integer Type::TypeID values for the 1, 8, 16, 32 and
   64-bit integers. These are replaced with just IntegerType which is not
   a primitive any more.
3. Adjust the rest of LLVM to account for this change.

Note that while this incremental change lays the foundation for arbitrary
bit-width integers, LLVM has not yet been converted to actually deal with
them in any significant way. Most optimization passes, for example, will
still only deal with the byte-width integer types.  Future increments
will rectify this situation.

cdaf88ff9d For PR411: 
Take an incremental step towards type plane elimination. This change

4bafa71dc1 For PR786: 
Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

783084211a For PR521: 
With these patches we implement the ability for the Linker library to

and cause their users to remove such files from the list of libraries to
pass to the native linker.

2b33292a67 Adjust the constructor to the Linker class to take an argument that names 
the module being constructed. This is used to correctly name the module.
Previously the name of the linker tool was used which produces confusing

5534b2d505 For PR495: 
Get rid of the difference between file paths and directory paths. The Path
class now simply stores a path that can refer to either a file or a
directory. This required various changes in the implementation and interface
of the class with the corresponding impact to its users. Doxygen comments were
also updated to reflect these changes. Interface changes are:

appendDirectory -> appendComponent
appendFile -> appendComponent
elideDirectory -> eraseComponent
elideFile -> eraseComponent
elideSuffix -> eraseSuffix
renameFile -> rename
setDirectory -> set
setFile -> set

Changes pass Dejagnu and llvm-test/SingleSource tests.
