2019-02-21beam_ssa_type: Use types from some 'lists' functionsBjörn Gustavsson
This commit lets the compiler know about the return type of some of the functions in the `lists` module. Knowing about the return will allow the compiler to emit fewer type test instructions, and also fewer instructions for throwing `case_clause` or `badmatch` exceptions, thus producing slightly faster and more compact code. This change makes the `lists` module a part of the language, but it could be argued that it already is because several functions (e.g. `member/2` and `keymember/3`) are implemented in as BIFs in the runtime system. Therefore, a user cannot simply change the `lists` module and expect everything to continue working as before. The compiler will now know the return types for the following functions: all/2 any/2 keymember/3 member/2 prefix/2 suffix/2 dropwhile/2 duplicate/2 filter/2 flatten/1 map/2 mapfoldl/3 mapfoldr/3 partition/2 reverse/1 sort/1 splitwith/1 takewhile/1 unzip/1 usort/1 zip/2 zipwith/3
2019-02-21sys_core_fold: Remove an unsafe optimizationBjörn Gustavsson
`sys_core_fold` has an optimization of repeated pattern matching. For example, when a record is matched the first time, the pattern is remembered. When the same record is matched again, the matching does not need to be repeated, but the variables bound in the first matching can be re-used. It turns out that that there is a name capture problem when the old inliner is used. The old inliner is used when explicitly inling certain functions, and by the compiler test suites for testing the compiler. The name capture problem could be eliminated by more aggressive variable renaming when inlining. But, fortunately, given the new SSA passes, this optimization is no longer as essential as it used to be. Removing the optimization turns out to be mostly benefical, leading to a smaller stack frame in many cases. Also remove the optimizations of `element/2`, `is_record/3`, and `setelement/3` from `sys_core_fold`. Because matched patterns are no longer remembered, those optimizations can very rarely be applied any more. (Those same optimizations are already done in `beam_ssa_type`.)

2019-02-21beam_ssa_opt: Do local CSE of get_tuple_element instructionsBjörn Gustavsson
For some reason, a `get_tuple_element` instruction was not deemed suitble for local common sub expression elimination. It turns out that enabling CSE for `get_tuple_element` is benefical. It will also be even more benefical in a future commit where some of the optimizations in `sys_core_fold` are removed.

In crashdump_viewer test, the helper module must be loaded on earlier releases (major-2), so it has a compiler directive. This was r18, but is now changed to r20.

While this is strictly only relevant for bs_get_binary2, we should never build anything while matching a message, so it ought to be safe to remove this last raw use of propagate_fragility.
