[Hexagon] NFC Using canonicalizePacket to compound/duplex/pad packets rather than doing it separately.  This also ensures the integrated assembler path matches the assembly parser path.

We now just return values and let ValueMap handle the map.

Currently "<type> ptr <reg name>" treated as <reg name> in MS inline asm, ignoring the "<type> ptr" completely and possibly ignoring the intention of the user.
Fixed llvm to produce an error when encountering "<type> ptr <reg name>" operands.

For example: andpd xmm1,xmmword ptr xmm1 --> andpd xmm1, xmm1 
though andpd has 2 possible matching formats - andpd xmm, xmm/m128

It is not enough to simply make the destructor virtual since there is a g++ 4.7
issue (see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53613) that throws the
error "looser throw specifier for ... overridding ~SCEVPredicate() noexcept".

[TableGen] Remove an assumption about the order of encodings in the MVT::SimpleValueType enum. Instead of assuming the types are sorted by size, scan the typeset arrays to find the smallest/largest type. NFC

This works mostly fine but breaks some stage 1 builders when compiling
compiler-rt on i386. Revert for further investigation as I can't see an
obvious cause/fix.

This reverts commit r254577.

There is no real reason the index has to have the concept of an
exporting Module. We should be able to have one single unique
instance of the Index, and it should be read-only after creation
for the whole ThinLTO processing.
The linker plugin should be able to process multiple modules (in
parallel or in sequence) with the same index.

The only reason the ExportingModule was present seems to be to
implement hasExportedFunctions() that is used by the Module linker
to decide what to do with the current Module.
For now I replaced it with a query to the map of Modules path to
see if this module was declared in the Index and consider that if
it is the case then it is probably exporting function.
On the long term the Linker interface needs to evolve and this
call should not be needed anymore.

The new algorithm remembers the uses encountered while walking backwards
until a matching def is found. Contrary to the previous version this:
- Works without LiveIntervals being available
- Allows to increase the precision to subregisters/lanemasks
  (not used for now)

The changes in the AMDGPU tests are necessary because the R600 scheduler
is not stable with respect to the order of nodes in the ready queues.

This replaces DoNotLinkFromSource with ValuesToLink. It also moves the
computation of ValuesToLink earlier.

It is a bit simpler and an important step in slitting the linker into an
ir mover and a linker proper.

The test change is because we now avoid creating dead declarations.

Having to import an alias as declaration is not thinlto specific.

The test difference are because when we already have a decl and we are
not importing it, we just leave the decl alone.
