1. Fixed typo. lenght -> length. Arbitary -> Arbitrary.
2. TypedArray DataView property getters should throw TypeError when called on
    incompatible types.
3. Should not use integers as keys in the arbitrary-properties test.

Prevent snapshot_blob.bin from being unnecessarily generated when building all targets.
When such file exists, chrome_tests assumes we will load V8's initial snapshot from
external files, even when such feature is turned off, which prevents the tests from
being successfully compiled.

The problem was that there can be several multi-byte UTF-8 characters near the
splitting point of the data chunks, and the code didn't handle it properly.

This was also the source of crbug.com/417891 - I thought the crash can only
happen when V8 is passed invalid UTF-8 data, but it can also happen in the
abovementioned case. After the fix, we handle the valid UTF-8 case and also
guard against invalid UTF-8 data.

This is required to fix a tricky branch fusion bug on ARM, which was
caused by the interaction between the architecture-independent and
architecture-specific parts of the InstructionSelector. In the end it
wasn't worth sharing a few common lines of code for the additional
complexity, especially if we also want to properly support architectures
without any dedicated flags register (i.e. MIPS).

This is basically https://codereview.chromium.org/569573002/ done right:

During construction, each node type tells its parent how many IDs it
needs in addition to the parent's ones. This is done all the way up in
the class hierarchy until a node's parent doesn't need any ID. At that
point we know how many IDs in summary are needed, and we reserve the
whole range at once, saving only the base ID of that range. All IDs
are now calculated via simple offsets to that base ID. To all
performaniacs: The C++ compiler simplifies the constant calculation to
a simple load and the addition of a single constant.

Note that the actual code is much simpler than all that prose above. :-)
It's basically how compilers for OO languages figure out vtable entries.

We still have lots of holes due to padding in the AST nodes, but this
will be addressed in a separate CL.

ES5.1 section 6 ("Source Text"):
"Throughout the rest of this document, the phrase “code unit” and the
word “character” will be used to refer to a 16-bit unsigned value
used to represent a single 16-bit unit of text."

This changed in ES6 draft section 10.1 ("Source Text"):
"The ECMAScript code is expressed using Unicode, version 5.1 or later.
ECMAScript source text is a sequence of code points. All Unicode code
point values from U+0000 to U+10FFFF, including surrogate code points,
may occur in source text where permitted by the ECMAScript grammars."

This patch is to reflect this spec change.
