When stepping in from JS, the stepping frame ID will not be set. Instead of ensuring to set it properly, we can just skip the check for the frame ID. It was needed before, when we didn't properly reset stepping information. Now, it's redundant anyway. Also, ensure that we don't redirect to the interpreter if the --debug-in-liftoff flag is set. Drive-by: Fix and clang-format some parts of the test (no semantic change).

LoadTransform is not implemented on BE machines and instead, it is divided into 2 separate "Load" and "operation" nodes. We need to assure same behaviour applies on S390 simulator, however, S390 Sim does not execute BE code, it assume generated code is in LE format hence "V8_TARGET_BIG_ENDIAN" is set to false when running on Sim. This CL includes V8_TARGET_ARCH_S390_LE_SIM to assure same behaviour occurs when running on the Sim until V8_TARGET_BIG_ENDIAN can also include the simulator.

All 6 replace_lane operations for ARM and ARM64. Changes to wasm-compiler required for ARM (where register aliasing is different - 2 fp registers map to 1 simd register). When src2_rc is kFpReg, and src1_rc is kFpRegPair, we still need to pin src2 when getting a register for src1, since the registers can overlap. (On other backends, src1_rc == src2_rc == kFpReg, so the current condition is met, and we correctly pin src2). Same for result_rc and src2_rc.

DebugInfo::RemoveBreakpoint did not remove the correct breakpoint because of a confusion between offsets relative to the function and offsets relative to the module. This is not visible in the tests, as removed breakpoints are already skipped by the runtime function. Drive-by: replace a return which should have been a continue in OSR.

There are only three tests with differing behaviour if Liftoff is used for debugging. This CL thus stages the --debug-in-liftoff flag behind --future (tested by the "future" variant) and excludes the three tests. This allows us to test the other (already working) tests for regressions, and iteratively shrinking down the list of failing tests. Drive-by: Tier down modules in tests before testing debugging features to avoid hitting a DCHECK in Liftoff recompilation for debugging.

This is a minor cosmetic fix. Wasm opcodes are bytes, hence they should always be printed as an even number of hexadecimal digits. Note that currently we only print a single byte anyway, but in the future we will want to extend this to correctly parse multi-byte opcodes. Those will also be printed as an even number of characters then.

The asm-wasm-f32 and asm-wasm-f64 tests run through a bunch of different constants. For the binops, they run through a cross product of the inputs. This patch trims down the number of constants used. The selection of constants to remove is quite arbitrary - the intial patch introduced a lot of magic constants that look random or has some pattern. I don't think they mean anything special, especially for f64 form since those values all fit in a f64. For f32 we still have a bunch of values to exceed the maximum integer representable in f32.

Rework testMemoryGrowPreservesDataMemOp tests so that they only test the first and last 5 offsets within the page, instead of every offset. Slight logic change: instead of storing the value C - offset (where C is a constant that is different for 32 and 16 memops), we store just the value offset. This allows us to combine the logic for all 3 memops (32, 16, and 8). But we need to add a modulo so that in the 8 bit case, we don't store a value that exceeds the maximum (the other cases will never hit a case that exceeds the max).

Most control structures in WebAssembly do not have a clear execution semantics, they are more like markers. Hence the execute state, and the change in the state, when breaking on them and stepping over them is unclear. Hence this CL just makes them non-breakable. If the user tries to set a breakpoint on them, this breakpoint will automatically be propagated to the first instruction after the respective control opcode (this is tested for other cases in existing tests).
