packed types with an element count of 1, although more generic support is
coming.  This allows LLVM to turn the following code:

void %foo(<1 x float> * %a) {
entry:
  %tmp1 = load <1 x float> * %a;
  %tmp2 = add <1 x float> %tmp1, %tmp1
  store <1 x float> %tmp2, <1 x float> *%a
  ret void
}

Into:

_foo:
        lfs f0, 0(r3)
        fadds f0, f0, f0
        stfs f0, 0(r3)
        blr

l1__2E_str_1:                           ; '.str_1'
        .asciz  "foo"

not:

        .align  0
l1__2E_str_1:                           ; '.str_1'
        .asciz  "foo"

llvm-svn: 24273

add support for .asciz, and enable it by default.  If your target assemblerdoesn't support .asciz, just set AscizDirective to null in your asmprinter.
This compiles C strings to:

l1__2E_str_1:                           ; '.str_1'
        .asciz  "foo"

instead of:

l1__2E_str_1:                           ; '.str_1'
        .ascii  "foo\000"

Switch the allnodes list from a vector of pointers to an ilist of nodes.This eliminates the vector, allows constant time removal of a node froma graph, and makes iteration over the all nodes list stable when adding
nodes to the graph.

turn power-of-two multiplies into shifts early to improve compile time.

Change the ValueList array for each node to be shared instead of individuallyallocated.  Further, in the common case where a node has a single value, justreference an element from a small array.  This is a small compile-time win.

llvm-svn: 24251

Switch the operandlist/valuelist from being vectors to being just an array.This saves 12 bytes from SDNode, but doesn't speed things up substantially
(our graphs apparently already fit within the cache on my g5).  In any case
this reduces memory usage.

set and eliminating the need to iterate whenever something is removed (which
can be really slow in some cases).  Thx to Jim for pointing out something silly
I was getting stuck on. :)

alignment information appropriately.  Includes code for PowerPC to support
fixed-size allocas with alignment larger than the stack.  Support for
arbitrarily aligned dynamic allocas coming soon.
