7a4ed9d200 Revert "using the original sourcemap as the base"
This reverts commit ad18689d92.

Reason for revert: introduce issue #882

Currently, generated sourcemap contains copy of all existing mappings and adds new mappings from uglified code to original one.
However, previous mapping are no longer valid and shouldn't be added.

7691bebea5 Rework has_directive
It's now available during tree walking, i.e. walker.has_directive("use
asm"), rather than as part of the scope.  It's thus no longer necessary
to call `figure_out_scope` before codegen.  Added special bits in the
code generator to overcome the fact that it doesn't inherit from
TreeWalker.
