Fix bug restoring of JS entry sp so to fix profiler-related valgrind issues.

Fix bug restoring of JS entry sp so to fix profiler-related valgrind issues.

The profiler did not correctly identify when there was a JS frame
on the stack after an exception was thrown.

I also refactored the code to use PopTryHandler macro-instructions on all platforms

BUG=73722
TEST=No more valgrind errors related to v8::internal::StackFrameIterator.
