Arm64: Fix PackedSwitch codegen for large methods.

This patch fixes a bug in arm64 PackedSwitch code generation
for very large methods where we exceeded the range of Adr
instruction - jump tables were emited in the very end of the
method. Instead we now emit the jump table in-place as part of
the PackedSwitch visitor - in the same way how it is done
in arm32 backend.

This patch also removes an incorrect assumption that the size of
a method has a linear dependency on the number of its HIR
instructions. This was used to choose whether to emit a jump
table for a PackedSwitch.
