virtual registers possibly having multiple kills while still
being defined and killed in the same block. If LiveIntervals
is manually re-run after two-address lowering, it currently
does add extra kills to two-address instructions, but this
is considered a bug.

x87 virtual registers are used, to avoid doing any work in the
common case that no x87 code is needed.

When constructing std::strings from C strings, we should check the input
value to be not NULL so that the std::string constructor does not
segfault.
Fixes #3047.

that it no longer handles non-power-of-two vectors.
However it previously only handled them sometimes,
depending on obscure numerical relationships between
the index and vector type.  For example, for a vector
of length 6, it would succeed if and only if the
index was an even multiple of 6.  I consider this
more confusing than useful.

are now inserted by PopulateCompilationGraph(). This should cut down

This lets several failing tests get farther along, but doesn't completely fix any of them.
