Chris Lattner 12b0831295 Make this more efficient of the common case where we are only mangling globals.
Do not mangle internal global names that do not collide with anything.

This gives us strings that now look like this:

__2E_str_1:                             ; '.str_1'
        .asciz  "foo"

instead of this:

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

Chris Lattner 55a6d9067b 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"

Chris Lattner bf4f233214 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.

Chris Lattner 7e4b5d33cb 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.

Chris Lattner aba48dd34c Clean up RemoveDeadNodes significantly, by eliminating the need for a temporary
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. :)

Nate Begeman 3ee3e69556 Add the necessary support to the ISel to allow targets to codegen the new
alignment information appropriately.  Includes code for PowerPC to support
fixed-size allocas with alignment larger than the stack.  Support for
