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.

Fixes #1044

187a0caf9d Add base54.reset() to compress tests 
Without this reset, char counts bleed to next tests. One test had a bad expect clause.

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

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However, previous mapping are no longer valid and shouldn't be added.

Running `uglifyjs --verbose --compress --mangle --screw-ie8 class.js`
with
`class.js`:

```
Fails with:
```
undefined:4041
  return this.definition().unmangleable(options);
TypeError: Cannot read property 'unmangleable' of undefined
