1628cec4d7 For PR950: 
Make necessary changes to support DIV -> [SUF]Div. This changes llvm to
have three division instructions: signed, unsigned, floating point. The
bytecode and assembler are bacwards compatible, however.

cf7ff2b4c8 Add support for the new "target data" information in .ll files. This provides 
a better encoding of the targets data layout, rather than trying to guess it
from the endianness and pointersize like before.

b74ed07bfd Adding dllimport, dllexport and external weak linkage types. 
DLL* linkages got full (I hope) codegeneration support in C & both x86
assembler backends.
External weak linkage added for future use, we don't provide any
codegeneration, etc. support for it.

61c83e023f For PR797: 
Rid the Assembly Parser of exceptions. This is a really gross hack but it
will do until the Assembly Parser is re-written as a recursive descent.
The basic premise is that wherever the old "ThrowException" function was
called (new name: GenerateError) we set a flag (TriggerError). Every
production checks that flag and calls YYERROR if it is set. Additionally,
each call to ThrowException in the grammar is replaced with GEN_ERROR
which calls GenerateError and then YYERROR immediately. This prevents
the remaining production from continuing after an error condition.

Add support for specifying alignment and size of setjmp jmpbufs.

No targets currently do anything with this information, nor is it presrved
in the bytecode representation.  That's coming up next.

1c7b907325 Okay, the list of link-time passes wasn't such a hot idea. Its prone to 
error. We'll strategize on this when we have multiple front ends to deal
with. For now llvm-ld just runs a standard set of transforms.
