ddb93e7a02 Turn StripPointerCast() into a method

ef80f5dbca If weak GlobalVariable was bitcast'ed to different type during linking 
we will need to strip all casts for intializer lookup.

b54defaff0 Replace calls of the form V1->setName(V2->getName()) with V1->takeName(V2), 
which is significantly more efficient.

d141d16ed7 Change the MemoryBuffer::getFile* methods to take just a pointer to the 
start of a filename, not a filename+length.  All clients can produce a
null terminated name, and the system api's require null terminated 
strings anyway.

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.

2de224be98 Fix PR1611 - Visibility should be ignored for a declaration 
when a definition's visibility is different.  Likewise, the
visibility of two declarations mismatching is not an error.

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.

db43279e9a If an archive is not recognized as an LLVM bytecode archive then declare 
that it is native so that the linker will pass it on downstream. This avoids
a problem where the native link line fails because there is both a .so and
a .a file. The .a file gets processed as bytecode and then dropped from the
command line.
