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.

cb66ae964e Finish removal of EH usage from the Archive library. The REQUIRES_EH flag
in lib/Bytecode/Archive/Makefile is now removed. One small step closer to
a smaller LLVM.

574dbee63c speed up Archive::isBytecodeArchive in the case when the archive doesn't have
an llvm-ranlib symtab.  This speeds up gccld -native on an almost empty .o file
from 1.63s to 0.18s.

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.

1c4d0a214a Correct the computation of when to add the padding. It is not based on the
member's size. It is based on the oddness/evenness of the file pointer.
This fixes a bug with llvm-ar not being able to read archives produced by
llvm-ranlib when there are members with odd long file name lengths.
