Richard van Velzen 27eedbc302 Never produce -0 when evaluating expressions (like -"")
Fix for #1085. The major case was already there, but more expressions can result in -0.

Richard van Velzen 8571a08a93 Do not attempt evaluating class expressions
Broadly the same as function expressions - these actually are statements but
we're limited by the inheritance tree.

Fábio Santos 634f231b78 First class block scope
- Make let, const, and class symbols be declared in a block scope.
- Piggy back on existing catch symbol implementation to get block-aware mangling working
- Make sure unused block-scoped declarations can be dropped
- Don't eliminate a block if it has a block-scoped declaration
- Remove silly empty anonymous blocks left over from drop_unused
- AST_Toplevel now gets to call drop_unused too, since block-scoped variables aren't global!
- Don't consider block declarations global

sergeyv 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However, previous mapping are no longer valid and shouldn't be added.
