Daniel Sanders 4a17dae631 [globalisel][tablegen] Fix an issue with lambdas when compiling with older GCC's
It seems that G++ 4.8 doesn't accept the 'enum A' in code of the form:
  enum A { ... };
  const auto &F = []() -> enum A { ... };
However, it does accept:
  typedef enum { ... } A;
  const auto &F = []() -> A { ... };

Simon Pilgrim 9d7863b935 [DAGCombiner] Match non-uniform constant vectors using predicates.
Most combines currently recognise scalar and splat-vector constants, but not non-uniform vector constants.

This patch introduces a matching mechanism that uses predicates to check against BUILD_VECTOR of ConstantSDNode, as well as scalar ConstantSDNode cases.

I've changed a couple of predicates to demonstrate - the combine-shl changes add currently unsupported cases, while the MatchRotate replaces an existing mechanism.

Daniel Sanders 7aac7cc57f [globalisel][tablegen] Add control-flow to the MatchTable.
Summary:
This will allow us to merge the various sub-tables into a single table. This is a
compile-time saving at this point. However, this will also enable the optimization
of a table so that similar instructions can be tested together, reducing the time
spent on the matching the code.

The bulk of this patch is a mechanical conversion to the new MatchTable object
which is responsible for tracking label definitions and filling in the index of
the jump targets. It is also responsible for nicely formatting the table.

This was necessary to support the new GIM_Try opcode which takes the index to
jump to if the match should fail. This value is unknown during table
construction and is filled in during emission. To support nesting try-blocks
(although we currently don't emit tables with nested try-blocks), GIM_Reject
has been re-introduced to explicitly exit a try-block or fail the overall match
if there are no active try-blocks.

This fixes cases on ARM64 when importing from more than one DLL,
in case the imports from the first DLL ended up unaligned.

When fixing up a IMAGE_REL_ARM64_PAGEOFFSET_12L, which shifts the
offset by the load/store size, check that the shift doesn't discard
any bits. (This would also detect if the import address chunks were
unaligned.)

Matt Arsenault 04004716ff AMDGPU: Correct encoding for global instructions
The soffset field needs to be be set to 0x7f to disable it,
not 0. 0 is interpreted as an SGPR offset.

This should be enough to get basic usage of the global instructions
working. Technically it is possible to use an SGPR_32 offset,
but I'm not sure if it's correct with 64-bit pointers, but
that is not handled now. This should also be cleaned up
to be more similar to how different MUBUF modes are handled,
and to have InstrMappings between the different types.

Peter Szecsi cb387b11df This feature allows the analyzer to consider loops to completely unroll. New
requirements/rules (for unrolling) can be added easily via ASTMatchers.

The current implementation is hidden behind a flag.

Right now the blocks which belong to an unrolled loop are marked by the 
LoopVisitor which adds them to the ProgramState. Then whenever we encounter a
CFGBlock in the processCFGBlockEntrance which is marked then we skip its
investigating. That means, it won't be considered to be visited more than the
maximal bound for visiting since it won't be checked.
