otherwise the SmallVector it contains doesn't free its memory.
In most cases LiveIntervalAnalysis could get away by not calling the destructor,
because VNInfos are bumpptr-allocated, and smallvectors usually don't grow.
However when the SmallVector does grow it always leaks.
This is the valgrind shown leak from the original testcase:

I have audited all getOperandNo calls now, fixing
hidden assumptions. CallSite related uglyness will
be eliminated successively.
Note this patch has a long and griveous history,
for all the back-and-forths have a look at
CallSite.h's log.

ISD node. The only change in the generated isel code are comments
like:
< // Src: (X86dec_flag:i16 GR16:i16:$src)
---
> // Src: (X86dec_flag:i16:i32 GR16:i16:$src)
because now it knows that X86dec_flag returns both an i16 (for the result)
and an i32 (for EFLAGS) in this case. Wewt.

This is work in progress. So far, SSE execution domain tables are added to
X86InstrInfo, and a skeleton pass is enabled with -sse-domain-fix.

for the noinline attribute, and make the inliner refuse to
inline a call site when the call site is marked noinline even
if the callee isn't. This fixes PR6682.
