Jakob Stoklund Olesen 2a82333f54 Don't include alignment padding in BBInfo.Size. 
Compute alignment padding before and after basic blocks dynamically.

Heed basic block alignment.

This simplifies bookkeeping because we don't have to constantly add and
remove padding from BBInfo.Size.  It also makes it possible to track the
extra known alignment bits we get after a tBR_JTr terminator and when
entering an aligned basic block.

This makes the ARMConstantIslandPass aware of aligned basic blocks.

It is tricky to model block alignment correctly when dealing with inline
assembly and tBR_JTr instructions that have variable size.  If inline
assembly turns out to be smaller than expected, that may cause following
alignment padding to be larger than expected.  This could cause constant
pool entries to move out of range.

To avoid that problem, we use the worst case alignment padding following
inline assembly. This may cause slightly suboptimal constant island
placement in aligned basic blocks following inline assembly.  Normal
functions should be unaffected.

Sean Callanan 610baf42ce Fixed a few details of method lookup in Objective-C 
symbols.  Now we find the correct method.

Unfortunately we don't get the superclass from the
runtime yet so the method doesn't import correctly
(and I added a check to make sure that doesn't hurt
us) but once we get that information right we will
report methods correctly to the parser as well.

Getting superclass information requires a common AST
context for all Objective-C runtime information,
meaning that the superclass and the subclass are in
the same AST context in all cases.  That is the next
thing that needs to be done here.

files.  First, add a new block USELIST_BLOCK to the bitcode format.  This is 
where USELIST_CODE_ENTRYs will be stored.  The format of the USELIST_CODE_ENTRYs
have not yet been defined.  Add support in the BitcodeReader for parsing the
USELIST_BLOCK.
