Chris Lattner b2c0e243c5 Make blockaddress(@func, null) be valid, and make 'deleting a basic 
block with a blockaddress still referring to it' replace the invalid 
blockaddress with a new blockaddress(@func, null) instead of a 
inttoptr(1).

This changes the bitcode encoding format, and still needs codegen 
support (this should produce a non-zero value, referring to the entry
block of the function would also be quite reasonable).

Chris Lattner a91a563530 Previously, all operands to Constant were themselves constant. 
In the new world order, BlockAddress can have a BasicBlock operand.
This doesn't permute much, because if you have a ConstantExpr (or
anything more specific than Constant) we still know the operand has
to be a Constant.

Chris Lattner d04cb6d0fa rename indbr -> indirectbr to appease the residents of #llvm.

Chris Lattner 3ed871fe62 add enough support for indirect branch for the feature test to pass 
(assembler,asmprinter, bc reader+writer) and document it.  Codegen
currently aborts on it.

Victor Hernandez de5ad42aa1 Remove FreeInst. 
Remove LowerAllocations pass.
Update some more passes to treate free calls just like they were treating FreeInst.

Dale Johannesen fd04c74bc0 Add an "msasm" flag to inline asm as suggested in PR 5125. 
A little ugliness is accepted to keep the binary file format
compatible.  No functional change yet.

Chris Lattner fdd8790718 strength reduce a ton of type equality tests to check the typeid (Through 
the new predicates I added) instead of going through a context and doing a
pointer comparison.  Besides being cheaper, this allows a smart compiler
to turn the if sequence into a switch.
