Check in code to scalarize arbitrarily wide packed types for some simple

This allows us to codegen:
void %foo(<4 x float> * %a) {
entry:
%tmp1 = load <4 x float> * %a;
%tmp2 = add <4 x float> %tmp1, %tmp1
store <4 x float> %tmp2, <4 x float> *%a
ret void
}
on ppc as:
_foo:
lfs f0, 12(r3)
lfs f1, 8(r3)
lfs f2, 4(r3)
lfs f3, 0(r3)

Add support for a cycle counter intrinsic. As basically all processors have
...
this and have it in about the same form, I think this makes sense.
on X86, you do a RDTSC (64bit result, from any ring since the P5MMX)
on Alpha, you do a RDCC
on PPC, there is a sequence which may or may not work depending on how things
are setup by the OS. Or something like that. Maybe someone who knows PPC
can add support. Something about the time base register.
on Sparc, you read %tick, which in some solaris versions (>=8) is readable by
userspace
on IA64 read ar.itc
So I think the ulong is justified since all of those are 64bit.
Support is slighly flaky on old chips (P5 and lower) and sometimes
depends on OS (PPC, Sparc). But for modern OS/Hardware (aka this decade),
we should be ok.
I am still not sure what to do about lowering. I can either see a lower to 0, to
gettimeofday (or the target os equivalent), or loudly complaining and refusing to
continue.
I am commiting an Alpha implementation. I will add the X86 implementation if I
have to (I have use of it in the near future), but if someone who knows that
backend (and the funky multi-register results) better wants to add it, it would
take them a lot less time ;)

Keep the killed/dead sets sorted, so that "KillsRegister" can do a quick

X86 from 10.8128s to 9.7943s, with no difference in generated code (like all
of the RA patches).
With these changes, isel is the slowest pass for PPC/X86, but linscan+live
intervals is still > 50% of the compile time for itanium. More work could
be done, but this is the last for now.

Eliminate the SetCCSDNode in favor of a CondCodeSDNode class. This pulls the
...
CC out of the SetCC operation, making SETCC a standard ternary operation and
CC's a standard DAG leaf. This will make it possible for other node to use
CC's as operands in the future...

Like constants, globals on some platforms are GOT relative. This means they have to be allocated
...
near the GOT, which new doesn't do. So break out the allocate into a new function.
Also move GOT index handling into JITResolver. This lets it update the mapping when a Lazy
function is JITed. It doesn't managed the table, just the mapping. Note that this is
still non-ideal, as any function that takes a function address should also take a GOT
index, but that is a lot of changes. The relocation resolve process updates any GOT entry
it sees is out of date.

Major refactor of the ELFWriter code. Instead of building up one big
...
vector that represents the .o file at once, build up a vector for each
section of the .o file. This is needed because the .o file writer needs
to be able to switch between sections as it emits them (e.g. switch
between the .text section and the .rel section when emitting code).
This patch has no functionality change.

Instead of storing std::string's for ExternalSymbol references, rely on the
...
fact that all ExternalSymbols are actually string literals with static storage.
Thus we don't have to do anything special to hold them and we certainly don't
have to copy string data around.

Allow machine operands to represent global variables with offsets. This is
...
useful when you have a reference like:
int A[100];
void foo() { A[10] = 1; }
In this case, &A[10] is a single constant and should be treated as such.
Only MO_GlobalAddress and MO_ExternalSymbol are allowed to use this field, no
other operand type is.
This is another fine patch contributed by Jeff Cohen!!

Too many changes in one commit:
...
1. LiveIntervals now implement a 4 slot per instruction model. Load,
Use, Def and a Store slot. This is required in order to correctly
represent caller saved register clobbering on function calls,
register reuse in the same instruction (def resues last use) and
also spill code added later by the allocator. The previous
representation (2 slots per instruction) was insufficient and as a
result was causing subtle bugs.
2. Fixes in spill code generation. This was the major cause of
failures in the test suite.
3. Linear scan now has core support for folding memory operands. This
is untested and not enabled (the live interval update function does
not attempt to fold loads/stores in instructions).
4. Lots of improvements in the debugging output of both live intervals
and linear scan. Give it a try... it is beautiful :-)
In summary the above fixes all the issues with the recent reserved
register elimination changes and get the allocator very close to the
next big step: folding memory operands.

Change MachineBasicBlock's vector of MachineInstr pointers into an

ilist of MachineInstr objects. This allows constant time removal and
insertion of MachineInstr instances from anywhere in each
