asiva 03ce33f80c [BUILD] - Initial CL to unfork the NNBD Dart SDK
- Flips the flag from --nnbd to --no-nnbd so that by default it builds
  the NNBD version
- using the --no-nnbd flag results in the SDK being built in a
  directory which has the 'Legacy' suffix added to it
  (e.g: out/DebugX64Legacy)
- the '--enable-experiment=non-nullable' flag still needs to be passed

Alexander Markov 2397862762 [vm/aot] Eliminate unnecessary try/catch and try/finally
This change adds an ability to replace

try {

} catch (...) {
 throw;
}

and

try {
  <body>
} finally {

with <body> into unreachable code elimination kernel transformation,
which is used in AOT. These constructs can appear after assert code is
removed.
