Using branch probability to guide critical edge splitting. Summary: The original heuristic to break critical edge during machine sink is relatively conservertive: when there is only one instruction sinkable to the critical edge, it is likely that the machine sink pass will not break the critical edge. This leads to many speculative instructions executed at runtime. However, with profile info, we could model the splitting benefits: if the critical edge has 50% taken rate, it would always be beneficial to split the critical edge to avoid the speculated runtime instructions. This patch uses profile to guide critical edge splitting in machine sink pass.

Reland r311957 [codeview] support more DW_OPs for more complete debug info Summary: Some variables show up in Visual Studio as "optimized out" even in -O0 -Od builds. This change fixes two issues that would cause this to happen. The first issue is that not all DIExpressions we generate were recognized by the CodeView writer. This has been addressed by adding support for DW_OP_constu, DW_OP_minus, and DW_OP_plus. The second issue is that we had no way to encode DW_OP_deref in CodeView. We get around that by changinge the type we encode in the debug info to be a reference to the type in the source code. This fixes PR34261. The reland adds two extra checks to the original: It checks if the DbgVariableLocation is valid before checking any of its fields, and it only emits ranges with nonzero registers.

[DIExpression] Introduce a dedicated DW_OP_LLVM_fragment operation so we can stop using DW_OP_bit_piece with the wrong semantics. The entire back story can be found here: http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20161114/405934.html The gist is that in LLVM we've been misinterpreting DW_OP_bit_piece's offset field to mean the offset into the source variable rather than the offset into the location at the top the DWARF expression stack. In order to be able to fix this in a subsequent patch, this patch introduces a dedicated DW_OP_LLVM_fragment operation with the semantics that we used to apply to DW_OP_bit_piece, which is what we actually need while inside of LLVM. This patch is complete with a bitcode upgrade for expressions using the old format. It does not yet fix the DWARF backend to use DW_OP_bit_piece correctly. Implementation note: We discussed several options for implementing this, including reserving a dedicated field in DIExpression for the fragment size and offset, but using an custom operator at the end of the expression works just fine and is more efficient because we then only pay for it when we need it.
