This CL introduces a new contextual 'LanguageSererData'. Its purpose
is to hold all the eagerly calculated data needed to answer
language server requests. The first thing collected are the
definitoins of some IdentifierExpresisons and macro/builtin
call-sites.

Collecting this data is not necessary for normal compilation, so it
is disabled by default and can be enabled via a Torque compiler
option. Since the holder class is a contextual for which no scope
exists during normal compilation, accidental collection of
unnecessary language server data *should* be prevented.

The SourceRangeAstVisitor has custom logic for blocks ending with a
statement that has a continuation range. In these cases, the trailing
continuation is removed which makes the reported coverage ranges a bit
nicer.

throw Error('foo') consists of an ExpressionStatement, with a
Throw expression stored within the statement. The source range itself
is stored with the Throw, not the statement.

We now properly extract the correct AST node for trailing throw
statements.

1. On Android, Skips mjsunit tests depending on setting LC_ALL env var.
2. With the cherrypick from ICU, locale "C" will no longer be
   canonicalized into "en-US-POSIX" since that is not part of a
   registered canonicalization. So on OS which there are no LANG,
   LC_CTYPE or LC_MESSAGE env vars, we need to also map that
   fallback locale "C" to "en-US".

This will allow the devtools UI to display private fields on the scope
panel.

Instead of extending GetInternalProperties, we expose a separate
GetPrivateFields method on the debug interface. This allows us to do
better type checking, for example, we can directly cast to a
v8::Private as this can only contain private fields.

This also allows us to have better constraints on the input type --
v8::Object, as opposed to a v8::Value.

The KeyAccumulator is extended to collect private names for the
PRIVATE_NAMES_ONLY PropertyFilter.

This is a port of the improvements to the ArgumentsAdaptorTrampoline
that previously landed for x64. It skips the arguments adaptor frame
creation if the callee cannot observe the actual arguments (as indicated
by the "is_safe_to_skip_arguments_adaptor" bit on the SharedFunctionInfo),
and instead just massages the current stack frame appropriately (either
by pushing more undefineds in case of under application, or by removing
the superfluous arguments in case of over application).
