using getValue instead of getAPIntValue.

When tailcallopt is enabled all fastcc calls must have an aligned argument stack size. Add a test case.

cmp-and-swap reversed the Cmp and Swap arguments; comments
make it clear this is unintentional.  Unfortunately, the
x86 BE had a compensating reversal, which is removed here.
PPC is OK.

From inspection of the Alpha code I think it is OK, but
if somebody has that platform please check it out.  I
cannot test on that platform.

If ISD::ANY_EXTEND fails, try ISD::ZERO_EXTEND and ISD::SIGN_EXTEND before giving up.  This fixes 445.gobmk on
X86-64 in fast isel.

__sync_fetch_and_nand as ANDC, even though that's
not what nand means.

to static allocas. As part of this change, refactor the
address mode code for laods and stores.

Fix a fastcc + sret bug. If fastcc and sret, callee doesn't need to pop the hidden struct ptr; Re-enable fastcc.

convention (not related to recent Ada testsuite
failures).

a slew of Ada testsuite failures on x86-32 linux.
Seems to be related to the use of float.

UsedDirective for some symbols in llvm.used into
Darwin-specific code.  I've decided LessPrivateGlobal
is potentially a useful abstraction and left it in
the target-independent area, with improved comment.

It's already special-cased and treated as rematerializable within
LiveIntervals; this allows it to be handled by other passes
such as TwoAddressInstrctionPass.

No functionality change.

Fix a constant lowering bug. Now we can do load and store instructions with funky getelementptr embedded in the address operand.

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).

Now with fix, which prevents subtle codegen bug to trigger on darwin.
No fix for bug though, it's still there.

Reverting r55898 to r55909. One of these patches was causing an ICE during the full bootstrap on Darwin:

Initial fastisel call support for C, Fast, and X86_FastCall calling conventions. It's meant to handle "simple" calls, i.e. no byval, structret, etc. It doesn't support multi-result returns either.

Not yet turned on, it needs to support sext / zext of arguments and result.
