Reland Fixes:
* Remove usage of C++11 vector members.
* Guard tests by V8_TURBO_TARGET.

Changes:
* Make context specialization clean up after itself.
* Add UpdateToAndIncrement to Inputs::iterator.
  Uses:iterator already provides this member function.
* Allow next node id in graph to be set.

The bit counting functions provided by CompilerIntrinsics were undefined
for zero, which was easily overlooked and unsafe in general. Also their
implementation was kinda hacky and mostly untested. Fixed the
implementation and moved the functions to base/bits.h.

These were front-ends to ToOperand32, to specify sign-extension.
However, since r22148, bits 63-32 are ignored for 32-bit operations
anyway, so there's no need for the caller to be explicit.
