05a4c0b1f2 Introducing the "linker_weak" linkage type. This will be used for Objective-C 
metadata types which should be marked as "weak", but which the linker will
remove upon final linkage. For example, the "objc_msgSend_fixup_alloc" symbol is
defined like this:

       .globl l_objc_msgSend_fixup_alloc
       .weak_definition l_objc_msgSend_fixup_alloc
       .section __DATA, __objc_msgrefs, coalesced
       .align 3
l_objc_msgSend_fixup_alloc:
        .quad   _objc_msgSend_fixup
        .quad   L_OBJC_METH_VAR_NAME_1

This is different from the "linker_private" linkage type, because it can't have
the metadata defined with ".weak_definition".

84321cc550 The variable ValueSize is set to 1 on both code paths, and then 
ignored!  Remove it.

5446bab8a5 The variable "Value" is carefully set to Layout.getSymbolAddress, 
but then not actually used - maybe a bug?  Remove the variable.

dbea6d7acb "This is just a cosmetic change in MCAsmStreamer.cpp/EmitSymbolAttribute: all attributes have now a \t before and after, as done for '.type'. 
This makes the output look consistent, as well as help some third party assemblers expecting the attributes to be in the second column."

Patch by Arnaud de Grandmaison!

cd585da505 Incorporate Daniel's suggestion and use !isdigit(CurPtr[0]) and not 
CurPtr[0] == '\n' when testing the character after a "0b" when looking
to see if it part of a something like "jmp 0b".

438a36f66a Fixed the problem with a branch to "0b" that was not parsed by llvm-mc 
correctly.  The Lexer was incorrectly eating the newline casusing it to branch
to address 0.  Updated the test case to use a "0:" label and a branch to "0b".
