6f287b22d2 Add the new `-no-builtin' flag. This flag is meant to mimic the GCC 
`-fno-builtin' flag. Currently, it's used to replace "memset" with "_bzero"
instead of "__bzero" on Darwin10+. This arguably violates the meaning of this
flag, but is currently sufficient. The meaning of this flag should become more
specific over time.

86098bd6a6 Add "inreg" field to CallSDNode (doesn't increase 
its size).  Adjust various lowering functions to
pass this info through from CallInst.  Use it to
implement sseregparm returns on X86.  Remove
X86_ssecall calling convention.

095cc29f32 Define CallSDNode, an SDNode subclass for use with ISD::CALL. 
Currently it just holds the calling convention and flags
for isVarArgs and isTailCall.

And it has several utility methods, which eliminate magic
5+2*i and similar index computations in several places.

CallSDNodes are not CSE'd. Teach UpdateNodeOperands to handle
nodes that are not CSE'd gracefully.

d2e51af035 Move the uglier parts of deciding not to emit a 
UsedDirective for some symbols in llvm.used into

is potentially a useful abstraction and left it in
the target-independent area, with improved comment.

b2dfb89e0e Fix logic for not emitting no-dead-strip for some 
objects in llvm.used (thanks Anton).  Makes visible
the magic 'l' prefix for symbols on Darwin which are
to be passed through the assembler, then removed at
linktime (previously all references to this had been
hidden in the ObjC FE code, oh well).

3df24e667f Create HandlePHINodesInSuccessorBlocksFast, a version of 
HandlePHINodesInSuccessorBlocks that works FastISel-style. This
allows PHI nodes to be updated correctly while using FastISel.

This also involves some code reorganization; ValueMap and
MBBMap are now members of the FastISel class, so they needn't
be passed around explicitly anymore. Also, SelectInstructions
is changed to SelectInstruction, and only does one instruction
at a time.

e00a8a2a2e Split the ATOMIC NodeType's to include the size, e.g. 
ATOMIC_LOAD_ADD_{8,16,32,64} instead of ATOMIC_LOAD_ADD.
Increased the Hardcoded Constant OpActionsCapacity to match.
Large but boring; no functional change.

This is to support partial-word atomics on ppc; i8 is
not a valid type there, so by the time we get to lowering, the
ATOMIC_LOAD nodes looks the same whether the type was i8 or i32.
The information can be added to the AtomicSDNode, but that is the
largest SDNode; I don't fully understand the SDNode allocation,
but it is sensitive to the largest node size, so increasing
that must be bad.  This is the alternative.
