Make test-parsing faster: don't run parsing tests with all experimental flag combinations.

Instead, make it possible for indifidual tests to pass "always true flags" which
are not part of the varying flag set.

The downside is that if an experimental flag changes parsing of some of the
unrelated code snippets, it's noticed later (only after the flag is turned on by
default). But this is a reasonable trade off for faster tests.

Additional fix: Some tests (ErrorsFutureStrictReservedWords) were using
always_flags incorrectly (running two different tests with different
always_flags basically iterates over every flag combination anyway - most of
them twice).

Fix NativesCollection<.>::GetScriptName in natives-external.cc

As there's no associated bug, here's the issue:
- Some ES6 functionality in Chrome is presently broken; this fixes it.
- The natives (built-in libraries) can be accessed by their 'name'.
  This is used to active ES6 flags.
- Strangely enough, there's an id and a name, where the name is derived
  from the id as "native %s.js", with %s for the id.
- NativesCollection<.>::GetScriptName uses the name.
- NativesCollection<.>::GetIndex uses the id.
- Example:
  NativesCollection<EXPERIMENTAL>::GetIndex("harmony-string") -> 3
  NativesCollection<EXPERIMENTAL>::GetScriptName(3) -> "native harmony-string.js"
- Nobody knows why; it's quite mysterious.
- When introducing the "external startup data", I didn't fully understand this
  and used the id in both places.
- When the "external startup data" was turned on in Chrome, ES6 features broke
  in Chrome since the libraries could no longer be found.
- This CL fixes this and makes the external startup data behave just like the
  built-in version.

Set V8_CC_GNU or V8_CC_MSVC for clang in gcc / cl mode.

Also, remove V8_CC_CLANG since it's not read anywhere (and ideally shouldn't
be).

Clang tries to be compatible with gcc in clang mode, and with msvc in clang-cl
mode. It wants to go down the same code paths that these compilers want to go
down in most cases.

For example, V8PRIxPTR was set incorrectly on Windows 64-bit before this change
since macros.h assumed that checking for V8_CC_MSVC is enough to find LLP64
systems, but V8_CC_MSVC wasn't set for clang.  Most other existing checks for
V8_CC_MSVC should be taken for clang-cl too (and for the remaining ones,
clang-cl is happy with either code path).

Likewise, V8_IMMEDIATE_CRASH is currently set to a suboptimal value with clang
since __builtin_trap() is only used if V8_CC_GNU is set.

Including clang in the gcc and cl macros is also what chromium does.
