Adds support for intrinsics which can be called as stubs. Namely: - HasProperty - MathPow - NewObject - NumberToString - RegExpConstructResult - RegExpExec - Substring - ToString - ToName - ToLength - ToNumber - ToObject Also adds interface descriptors for stub calls which have arguments passed on the stack.

If the semaphore is stored as a local variable in {CompileInParallel}, then the semaphore was sometimes deallocated too early and caused the compilation tasks to crash. This only happens with libc-2.19, libc-2.21 fixes the problem.

This was necessary since certain named handlers didn't check the name beforehand, and could miss to LoadIC_Miss with a name convertible to an index. This is currently not supported anymore, so we can drop this path. We should make sure we miss to the right label instead.

This adds a dedicated test to make sure we don't try constant folding on checks (in this case CheckTaggedPointer), which would generate invalid code as we removing checks that guard the constant without knowing whether it's safe to do so.

Port f47b9e98 Original commit message: This adds a new BUILTIN frame type, which supports variable number of arguments for builtins implemented in hand-written native code (we will extend this mechanism to TurboFan builtins at some point). Convert the Math.max and Math.min builtins to construct a BUILTIN frame if required. This does not yet work for C++ builtins, but that'll be the next step.

Reland of https://codereview.chromium.org/2048703002/ Code like `let a; eval("var a;");` should throw a SyntaxError, not a TypeError (this caused a test262 failure.). However, the code `eval("function NaN() {}");` should actually throw a TypeError. This patch changes most cases of redeclaration errors from TypeError to SyntaxError. See the test mjsunit/regress/redeclaration-error-types for a thorough analysis with spec references.

Previously, an async arrow function would be parsed if any valid ConditionalExpression began with the identifier "async", and its following token was on the same line. So for example, `async.bar foo => 1` was parsed as a valid async arrow function. This patch corrects this behaviour by asserting that the following token is a valid arrow parameters start.
