Chris Lattner 1b9f9c5f67 Do not put internal symbols into the symbol table. This shrinks the symbol
table for archives in common cases, and prevents trying to resolve a
external reference with an internal reference.  This shrinks the libpython.a
symbol table from 126302 to 19770 bytes.

Chris Lattner ccf22fb182 Fix the regressions my User changes introduced. Apparently some parts of
LLVM make the very reasonable assumption that constant expressions will
have at least one operand! :)

Reid Spencer cd89ca3040 For PR351:
Use sys::MappedFile instead of ReadFileIntoAddressSpace and
UnmapFileFromAddressSpace. sys::MappedFile has the nice property that it
cleans up after itself so exception handling can be removed.

Chris Lattner e44907012a Eliminate this ugly hack. This was put back in when replaceAllUsesOf used
a different algorithm that was extremely inefficient for instructions with
many operands.

This reduces the time of this code snippet from .23s for 176.gcc to 0.03s
in a debug build, which speeds up total llvm-dis time just barely.

It's more of a code cleanup than a speedup.

- Rearrange output order to make more sense
- Make only the function level output count as "detailed"

- Implement new handlers for number of types, dependent libs, target triple

Reid Spencer 191aa30ac1 Bytecode Reader Cleanup:
- provide the correct conversion for ModuleBlockID in read_block (a potential

- install support for handleTypeList handler
- install support for handleDependentLibrary handler
- install support for handleTargetTriple handler
- clean up comments, output strings,
- ensure that processing function arguments doesn't SIGSEGV if one of the
  arguments is a null pointer (yeah, it happened .. weird)
- prepare for version 5 bytecode by documenting what will change.

Reid Spencer b2bdb943b5 bug 263:

bug 402:
- initial (compatible) cut at 24-bit types instead of 32-bit
- reduce size of block headers by 50%
Other:
- cleanup Writer by consolidating to one compilation unit, rem. other files
- use a std::vector instead of std::deque so the buffer can be allocated
  in multiples of 64KByte chunks rather than in multiples of some smaller

- Add documentation
- Convert input dependent asserts to error(...) so it throws instead.
Provide placeholder implementations of read_float and read_double that
still read in platform-specific endianess. When I figure out how to do
this without knowing the endianess of the platform, it will get implemented
correctly.

Reid Spencer 6a218134e3 Fix a backwards compatibility bug found by Tanya. In version 1.2, the
global type plane starts with a length and the TypeTyID value to identify
the type plane has having type definitions. This doesn't happen in 1.3
because the types are read from a known position in the file. However, the
TypeTyID must be read in (and ignored) if its a 1.2 bytecode file.

- Standardize case and style of method names.
- Eliminate unneeded header files
- Prepare for Type != Value (bug122) change by splitting Types into their
