Krzysztof Parzyszek 39d14f3bc3 Reapply r286080 with a phony change in Hexagon's CMakeLists.txt
Cmake has not recognized that Hexagon.td has a new dependency in
HexagonPatterns.td. All changes to that file were not visible to
the build bots.

This file is not used. The location assignment of call arguments and
return values is implemented directly in HexagonISelLowering.

Krzysztof Parzyszek e95e95521c [Hexagon] Implement DFA based hazard recognizer
The post register allocator scheduler can generate poor schedules
because the scoreboard hazard recognizer is unable to identify
hazards for Hexagon precisely. Instead, Hexagon should use a DFA
based hazard recognizer.

Patch by Brendon Cahoon.

Krzysztof Parzyszek 7793ddb043 [Hexagon] Optimize stack slot spills
Replace spills to memory with spills to registers, if possible. This
applies mostly to predicate registers (both scalar and vector), since
they are very limited in number. A spill of a predicate register may
happen even if there is a general-purpose register available. In cases
like this the stack spill/reload may be eliminated completely.

This optimization will consider all stack objects, regardless of where
they came from and try to match the live range of the stack slot with
a dead range of a register from an appropriate register class.

Krzysztof Parzyszek c09d630e50 RDF: Copy propagation
This is a very limited implementation of DFG-based copy propagation.
It only handles actual COPY instructions (does not handle other equivalents
such as add-immediate with a 0 operand).
The major limitation is that it does not update the DFG: that will be the
change required to make it more robust (hopefully coming up soon).

NAKAMURA Takumi 226e10edff [CMake] Let add_public_tablegen_target() provide intrinsics_gen, too.
I think, in principle, intrinsics_gen may be added explicitly.
That said, it can be added incidentally, since each target already has dependencies to llvm-tblgen.
Almost all source files depend on both CommonTaleGen and intrinsics_gen.

Explicit add_dependencies() have been pruned under lib/Target.

NAKAMURA Takumi ce746c6c49 [CMake] Let add_public_tablegen_target responsible to provide dependency to CommonTableGen.
add_public_tablegen_target adds *CommonTableGen to LLVM_COMMON_DEPENDS.
LLVM_COMMON_DEPENDS affects add_llvm_library (and other add_target stuff) within its scope.

Juergen Ributzka d12ccbd343 [weak vtables] Remove a bunch of weak vtables
This patch removes most of the trivial cases of weak vtables by pinning them to
a single object file. The memory leaks in this version have been fixed. Thanks

Alexey Samsonov 49109a279c Revert r194865 and r194874.
This change is incorrect. If you delete virtual destructor of both a base class
and a subclass, then the following code:
  Base *foo = new Child();
  delete foo;
will not cause the destructor for members of Child class. As a result, I observe
plently of memory leaks. Notable examples I investigated are:
ObjectBuffer and ObjectBufferStream, AttributeImpl and StringSAttributeImpl.
