[JSC] Clean up heap/MachineStackMarker by introducing USE(MACHINE_CONTEXT)
​https://bugs.webkit.org/show_bug.cgi?id=170770

Reviewed by Mark Lam.

Source/JavaScriptCore:

We use USE(MACHINE_CONTEXT) to clean up runtime/MachineContext.h. And
we clean up heap/MachineStackMarker.cpp by using MachineContext functions.

• heap/MachineStackMarker.cpp:

(JSC::MachineThreads::MachineThread::Registers::stackPointer):
(JSC::MachineThreads::MachineThread::Registers::framePointer):
(JSC::MachineThreads::MachineThread::Registers::instructionPointer):
(JSC::MachineThreads::MachineThread::Registers::llintPC):

• heap/MachineStackMarker.h:
• runtime/MachineContext.h:

(JSC::MachineContext::stackPointer):
(JSC::MachineContext::framePointer):
(JSC::MachineContext::instructionPointer):
(JSC::MachineContext::argumentPointer<1>):
(JSC::MachineContext::llintInstructionPointer):

Source/WTF:

We add a new define USE_MACHINE_CONTEXT, which becomes true if mcontext_t exists
and we know the way to retrieve values from mcontext_t.

• wtf/Platform.h:
• wtf/PlatformRegisters.h:
• wtf/ThreadingPthreads.cpp:

(WTF::Thread::getRegisters):
