change the strange MetadataContext::getMDs function to expose less
irrelevant internal implementation details to clients.

Revert 85678/85680. The decision is to stay with the current form of
indirectbr, thus we don't need "blockaddr(@func, null)". Eliminate it
for simplicity.

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

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).

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.

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

llvm-svn: 85351

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.

Update some more passes to treate free calls just like they were treating FreeInst.

Fix getMDs() interface such that it does not expose implementation details.

Using TrackingVH instead of WeakVH or WeakMetadataVH.

Fix getHandlerNames() interface. Now it populate clinet supplied small vector with handler names.

Remove MallocInst from LLVM Instructions.

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.
