Generate a BTI instruction at each target of an indirect branch (BR/BLR). An indirect branch that doesn't jump to a BTI instruction will generate an exception on a BTI-enabled core. On cores that do not support the BTI extension, the BTI instruction is a NOP. Targets of indirect branch instructions include, among other things, function entrypoints, exception handlers and jump tables. Lazy deopt exits can potentially be reached through an indirect branch when an exception is thrown, so they also get an additional BTI instruction.

Each assembler has it's own way to place breakpoints: - stop() for arm, mips*, ppc* and s390. - debug() for arm64. - int3() for ia32 and x64. We can mandate a macro-assembler `DebugBreak()` method that all should implement so one can place a breakpoint in a portable way using a macro-assembler. This way also assemblers are in line with TurboFan, CSA, Torque and Liftoff which all have a DebugBreak() facility.

This change moves the definitions of the bitfield flags used by Symbol and Map to Torque. Symbol could directly follow the pattern established by SharedFunctionInfo, but Map required some other changes: - Until now, Torque bitfield definitions have required unsigned types. I thought that this would be the least-surprising behavior, since we never sign-extend when decoding bitfield values. However, I believe that the amount of churn involved in making ElementsKind be unsigned outweighs the benefit we were getting from this restriction (and similar difficulties are likely to arise in converting other bitfield structs to Torque), so this CL updates Torque to allow signed bitfield values. - If we try to make Map extend from all of the generated classes that define its flags, we end up with class sizing problems because some compilers only apply empty base class optimization to the first in a row of empty base classes. We could work around this issue by generating macros instead of classes, but I took this as an opportunity for a minor clean-up instead: rather than having bitfield definitions for several different bitfield structs all jumbled together in Map, they can be split up. I think this makes the code a little easier to follow, but if others disagree I'm happy to implement macro generation instead.

This removes the support to emit runtime calls in Liftoff code and uses WebAssembly runtime stubs instead. Calls to such stubs are smaller and more efficient. They also use embedded builtins directly instead of the on-heap {Code} object trampolines. This also removes the last use of a runtime call that passes a dynamically loaded CEntry builtin from the macro assembler.

{WhichPowerOf2} is basically the same as {CountTrailingZeros}, with a restriction to powers of two. Since it does not use or depend on any v8 internals, it can be moved to src/base/bits.h. This CL also changes the implementation to use the CTZ builtin if available, and falls back to popcnt otherwise. Drive-by: Make it constexpr, and rename to {WhichPowerOfTwo}.

Port 213504b9 Original Commit Message: The code fields in a JSRegExp object now either contain irregexp compiled code or a trampoline to the interpreter. This way the code can be executed without explicitly checking if the regexp shall be interpreted or executed natively. In case of interpreted regexp the generated bytecode is now stored in its own fields instead of the code fields for Latin1 and UC16 respectively. The signatures of the jitted irregexp match and the regexp interpreter have been equalized.

Port 7b48dd55 Original Commit Message: This changes Generate_ContinueToBuiltinHelper to generate code to load the builtin address directly from the builtins table rather than going via the executable code in the trampoline's code object. The set up for Generate_ContinueToBuiltinHelper is changed so that the builtin index is stored on the stack in place of the builtin Code object which is no longer needed.

Since TurboAssembler::CallBuiltinPointer actually takes the builtin_index as input, rename the function to CallBuiltinByIndex.
