Port ae03752f Original Commit Message: This implements inspection of live registers on breakpoints in Liftoff. To that end, the frame pointer of the WasmDebugBreak frame is remembered when iterating the stack. Based on a platform-specific implementation of {WasmDebugBreakFrameConstants}, the offset of the respective register within that frame is computed, and the value is read from the frame. As a drive-by, the wasm debug side table is storing register codes as liftoff codes, which can also store register pairs (needed for i64 on 32-bit platforms, and for SIMD, which is not supported yet).

Port e47f9a9d Original Commit Message: The set of registers to spill was wrong. Instead of spilling wasm parameter registers (like the WasmCompileLazy builtin), we should spill all registers that are being used as Liftoff cache registers. This CL defines platform-specific WasmDebugBreakFrameConstants which hold the set of registers to spill. This set is used in the builtin, and will later be used for inspecting the spilled registers. In order to iterate bit sets more easily in both direction (MSB to LSB or LSB to MSB), we add a base::bits::IterateBits{,Backwards} method which provides the respective iterators.

This CL refactors the implementation of WASM->JS import wrappers in order to make the wrapper code shareable. Instead of specializing to the import index, we use a tuple as the object ref in the both the import and indirect tables. The tuple allows the wrapper code to load both the calling instance and the target callable, rather than relying on code specialization. This requires some tricky codegen machinery, because WASM call descriptors expect an instance argument in a given register, yet the wrappers receive a tuple, the code generator must generate a prologue that loads the instance (and the callable), since it is not possible to express this at the graph level.

Register configuration data is not the same as frame configuration data. This CL moves the last remnants of register configuration into the assembler files, to be with the other register configuration macros. Next step: extract this register configuration data into platform-specific files that can be included independent of the assembler.
