The previous %StringCharCodeAt runtime entry (and the inlined intrinsic)
are obsolete and not used anymore (except in dedicated tests for this
runtime function), so remove it. And rename the %StringCharCodeAtRT
function, which is actually used to %StringCharCodeAt instead to have
a consistent naming scheme for runtime fallbacks.

Add a sequential string type to the compiler, and transform
charCodeAt on SeqString into SeqStringCharCodeAt.
SeqStringCharCodeAt can handle one and two byte strings.

Code generated for checks starting with primitive receivers skips one step
in the usual prototype checking algorithm, so the holder must always be set.
Not setting the holder did not cause an immediate failure because our
primitives have additional hidden prototypes before the real prototypes.
These extra objects in the chain usually contain no properties and so
allowed the right holders to be selected.

In the shell sample don't print the result of executing a script, only
evaluating expressions.
Fixed issue when building samples on Windows using a shared V8
library. Added visibility option on Linux build which makes the
generated library 18% smaller.
Changed build system to accept multiple build modes in one build and
generate seperate objects, libraries and executables for each mode.
Removed deferred negation optimization (a * -b => -(a * b)) since this
visibly changes operand conversion order.
Improved parsing performance by introducing stack guard in preparsing.
Without a stack guard preparsing always bails out with stack overflow.
