Eric Christopher 1e3e8933ed Another possible bug. Stopgap until we can autogenerate tables and
constraint lengths.

Eric Christopher ca9b7bbaa1 Add a new parse hint for multi-letter constraints in inline asm.
Testcase will come when we use it.

Dale Johannesen e81d45d2cc Apply patch for use-after-free in InlineAsm constant handling,
PR 8522 / 8616046.  Test reduction, analysis and patch by Tim Deegan!
(However, review by someone who understands the classes here better
is welcome.  John Krum will return!)

Duncan Sands 19d0b47b1f There are two ways of checking for a given type, for example isa<PointerType>(T)
and T->isPointerTy().  Convert most instances of the first form to the second form.
Requested by Chris.

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 860df6e84c Keep track of *which* input constraint matches an output
constraint.  Reject asms where an output has multiple
input constraints tied to it.

Christopher Lamb edf0788758 Change the PointerType api for creating pointer types. The old functionality of PointerType::get() has become PointerType::getUnqual(), which returns a pointer in the generic address space. The new prototype of PointerType::get() requires both a type and an address space.

Gordon Henriksen 14a5569f4e Reverting dtor devirtualization patch.

Reid Spencer 5113dc5cfe For PR780:
1. Add #includes to LinkAllVMCore.h to get Mangler.o and InlineAsm.o
2. Make Mangler.h and InlineAsm.h use the macros to ensure linkage
3. Make each of the tools with --load options include LinkAllVMCore.h
This should be the last set of changes for this bug and 800.
