- Teach Expr::isConstantExpr() about InitListExpr's (and offsetof, since I noticed it was missing).
- Rename CheckInitializer() to CheckInitializerTypes().
- Removed the isStatic argument to CheckInitializerTypes() and all of it's subroutines. Checking for constant expressions is now done separately.
- Added CheckForConstantInitializer().

Likewise fix up a bunch of other libcalls.  While
there I remove NEG_F32 and NEG_F64 since they are
not used anywhere.  This fixes 9 Ada ACATS failures.

x86 backend where instructions were not marked maystore/mayload, and perf issues where
instructions were not marked neverHasSideEffects.  It would be really nice if we could
write patterns for copy instructions.

I have audited all the x86 instructions down to MOVDQAmr.  The flags on others and on
other targets are probably not right in all cases, but no clients currently use this
info that are enabled by default.

Also, instructions with any nodes that are SDNPMayLoad also read memory.

Add a isImmutable bit to StackObject. Fixed stack objects are immutable (in the function) unless specified otherwise.

returns uses, the third returns both.
