Owen Anderson 6c18d1aac0 Get rid of static constructors for pass registration. Instead, every pass exposes an initializeMyPassFunction(), which
must be called in the pass's constructor.  This function uses static dependency declarations to recursively initialize
the pass's dependencies.

Clients that only create passes through the createFooPass() APIs will require no changes.  Clients that want to use the
CommandLine options for passes will need to manually call the appropriate initialization functions in PassInitialization.h
before parsing commandline arguments.

I have tested this with all standard configurations of clang and llvm-gcc on Darwin.  It is possible that there are problems
with the static dependencies that will only be visible with non-standard options.  If you encounter any crash in pass
registration/creation, please send the testcase to me directly.

Dale Johannesen baa5d045c9 Add X86 MMX type to bitcode and Type.
(The Ada bindings probably need it too, but all the
obvious places to change say "do not edit this file".)

Chris Lattner 13ee795c42 remove unions from LLVM IR. They are severely buggy and not
being actively maintained, improved, or extended.

Dan Gohman a5a25036bb Don't use unsigned char for alignments in TargetData. There aren't
that many of these things, so the memory savings isn't significant,
and there are now situations where there can be alignments greater
than 128.

Owen Anderson 755aceb5d0 Don't use PassInfo* as a type identifier for passes. Instead, use the address of the static
ID member as the sole unique type identifier.  Clean up APIs related to this change.

Dan Gohman e1931fa676 Change TargetData's algorithm for computing defualt vector type
alignment to match what's used in clang and GCC for __alignof, rather
than trying to guess what Legalize is going to be doing.

Dan Gohman 4bd755419f Revert the recent alignment changes. They're broken for -Os because,
in particular, they end up aligning strings at 16-byte boundaries, and
there's no way for GlobalOpt to check OptForSize.

Dan Gohman 9b80f86e5b Revert r97064. Duncan pointed out that bitcasts are defined in
terms of store and load, which means bitcasting between scalar
integer and vector has endian-specific results, which undermines
this whole approach.

Dan Gohman 4b2b48daba Make getTypeSizeInBits work correctly for array types; it should return
the number of value bits, not the number of bits of allocation for in-memory
storage.

Make getTypeStoreSize and getTypeAllocSize work consistently for arrays and
vectors.

Fix several places in CodeGen which compute offsets into in-memory vectors
to use TargetData information.

This fixes PR1784.

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.

Chris Lattner 3072add73c add a method to get the alignment of an integer type even
when we don't have one laying around.  Useful if you don't
have an llvmcontext handy.
