dd15e30b25 [typedarray] Widen set fast path for JSTypedArray source arguments
Pull most JSTypedArray source arguments onto the fast path.

Same source & target elements-kinds simply call memmove. Other
combinations call directly into C and reuse ElementsAccessor logic.

Only overlapping source & target args with differing elements-kinds
remain on the slow runtime path.

0f2223c894 [test] Refactor getting test outcomes from statusfile.
Filtering by status file split to four parts:
1. Getting outcomes - reads both variant dependent and
independent outcomes, no more need to do it twice.
2. Checking unused rules - has a switch to check only variant
dependent/independent rules.
3. Reading flags - if outcome starts with '--' it is treated as a flag.
4. Actual filtering.

Outcomes removed from the testcase object, can be accessed
by call to its testsuite.

54637463a3 [test] Re-enable all Unicode property tests
The DEPS roll in f3a2e34d updated ICU to a version that includes
a fix for https://ssl.icu-project.org/trac/ticket/13462. As a
result, our Script_Extension data is now correct again.

This patch re-enables the Test262 tests that were failing due to this
ICU data bug.

159236ec25 [regexp] Update semantics of GetSubstitution with named captures
The specced semantics of GetSubstitution are expected to change in the
case of malformed named references, or named references to nonexistent
named groups. The former will evaluate to the identity replacement of
'$<', while the latter will result in replacement by the empty string.

ac6ed35a31 Reland "[async-iteration] implement spec-change to yield in async generators"
Per https://github.com/tc39/proposal-async-iteration/pull/102/files:

AsyncGeneratorResolve no longer unwraps a value component. Instead, the value is
unwrapped before the builtin call via Await, allowing Promise rejections to
affect the generator control flow.

Thus, all `yield <expr>` implicitly become `yield await <expr>`.

Additionally, `return <expr>` becomes `return await <expr>`. Finally, when the
generator is resumed with `.return()`, the parameter passed to .return() is
awaited before generator execution properly continues).

ee15703e6c [parser] Prohibit async functions and generators in invalid contexts
Async functions and generator declarations are only permitted as
StatementListItems, not as ExpressionStatements, and therefore not
as the entire body of an if statement, etc. Previously, they were
incorrectly permitted. However, ChakraCore and SpiderMonkey seem
to ban them in this context, and the feature was introduced relatively
recently, so it is likely to be web-compatible to ship the prohibition.

This patch also unifies the error message wording of async functions
and generators to ordinary functions, explaining more clearly what
the issue is.

1769f892ce [cleanup] Remove always-off support for tail calls
The tail call implementation is hidden behind the --harmony-tailcalls
flag, which is off-by-default (and has been unstaged since February).
It is known to be broken in a variety of cases, including clusterfuzz
security issues (see sample Chromium issues below). To avoid letting
the implementation bitrot further on trunk, this patch removes it.
