port 1b230799 (r34747) original commit message: Int64Add is lowered to a new turbofan operator, Int32AddPair. The new operator takes 4 inputs an generates 2 outputs. The inputs are the low word of the left input, high word of the left input, the low word of the right input, and high word of the right input. The ouputs are the low and high word of the result of the addition. BUG= Review URL: https://codereview.chromium.org/1806833002 Cr-Commit-Position: refs/heads/master@{#34803}

port ddc626e1 (r34546) original commit message: I64Shl is lowered to a new turbofan operator, WasmWord64Shl. The new operator takes 3 inputs, the low-word input, the high-word input, and the shift, and produces 2 output, the low-word output and the high-word output. At the moment I implemented the lowering only for ia32, but I think the CL is already big enough. I will add the other platforms in separate CLs.

port 0e43ff56 (r34187) original commit message: The InstructionSelector now associates an effect level to every node in a block. The effect level of a node is the number of non-eliminatable nodes encountered from the beginning of the block to the node itself. With this change, on ia32 and x64, a load from memory into a register can be replaced by a memory operand if all of the following conditions hold: 1. The only use of the load is in a 32 or 64 bit word comparison. 2. The user node and the load node belong to the same block. 3. The values of the operands have the same size (i.e., no need to zero-extend or sign-extend the result of the load).

The operations were available on ARM64 and x86-32 but were unused. It has been conjectured that nontemporals can be used for rowhammer-like bitflips more easily than regular load/store operations. It is therefore desirable to avoid generating these instructions in the future.

This patch includes the following changes. 1, Enable the turbofan backend support for X87 platform. It depends on previous CL: 3fdfebd2. 2, Enable the test cases which are disabled because turbofan for X87 was not enabled.

port abc35080 (r28339) original commit message: This stub will be used as the basis of a Math.floor-specific CallIC to detect and track calls to floor that return -0. Along the way: - Create a TurboFanCodeStub super class from which the StringLength and MathRound TF stubs derive. - Fix the ugly hack that passes the first stub parameter as the "this" pointer in the the TF-compiled JS function. - Fix bugs in the ia32/x64 disassembler.

This improves the generated code for HSeqStringSetChar across all platforms, taking advantage of constant operands whenever possible. It also drops the unused DefineSameAsFirst constraint for the register allocator on x64 and ia32, where it caused unnecessary spills when the string operand was live across the HSeqStringSetChar instruction. A new GVN flag StringChars is introduced to express dependencies between HSeqStringSetChar, HStringCharCodeAt and the upcoming HSeqStringGetChar (the GVNFlags type is now 64bit in size). Also improves the test case.
