Reland 'Additional HandleScopes to limit Handle consumption.'
v8 builds with --no-snap were hitting handle limits compiling natives for handle count unit tests that run with --check_handle_count. Patch now has higher handle limits (~4k more than required for failing natives compilation).

Additional HandleScopes to limit Handle consumption.
erikcorry@chromium.org suggested digging into v8 handle usage. Found potential scopes in ast.cc and runtime-literals.cc and added tests.
The runtime-literals.cc change reduces peak handles in imaging-darkroom.js from 1,282,610 to 428,218. The ast.cc change reduces the peak handles in string-tagcloud.js from 80,738 to 8,176.
No significant handle count issues found with major websites, but substantial savings on some benchmarks and demos:
Kraken's imaging-darkroom.js down from 1,282,610 to 428,218 due to runtime-literals.cc scope.
SunSpider's string-tagcloud.js down from 80,738 to 8.176 due to ast.cc
