X87: Switch full-codegen from StackHandlers to handler table.

X87:  Switch full-codegen from StackHandlers to handler table.

port 38a719f965d0a83ddac04392d5b9c5abe214281c  (r27440)

original commit message:

    This switches full-codegen to no longer push and pop StackHandler
    markers onto the operand stack, but relies on a range-based handler
    table instead. We only use StackHandlers in JSEntryStubs to mark the
    transition from C to JS code.

    Note that this makes deoptimization and OSR from within any try-block
    work out of the box, makes the non-exception paths faster and should
    overall be neutral on the memory footprint (pros).

    On the other hand it makes the exception paths slower and actually
    throwing and exception more expensive (cons).
