8de62c64dc Fix missed "+0.5" rounding - use rint() instead
In commit 23baf20f56 (Use "rint()" instead of rounding manually with
"+ 0.5") I had missed this one remaining place where we rounded things
by adding "+0.5" and then truncated.

Fix that up.

2d0cf4a87a micro-optimisation: avoid division in main strtod() loop
Division is expensive, so replace it with multiplication instead.  But
don't multiply by 0.1 (inexact in floating point), multiply by 10 and
then do one division at the end.

Make sure the final division is at the very end, so that the result
isn't immediately used.  That allow the division to overlap with the
function return overhead, hiding it further.

This is silly, but while thinking about different file formats and doing
profiling of loading big files, it turned out that "strtod_flags()"
actually showed up in profiles. Not very high, but at more than 1%.

This makes the common case (no exponent) use only addition and
multiplication until the very end, and makes the division be the very last
thing it does, which minimizes the data dependencies on the division.

For my stupid test-case, it cut the cost of strtod_flags() in half
according to the profile. The half a percent speedup on loading time isn't
really noticeable or even measurable outside of profiling startup costs,
but rather than carry this along in my tree or just throw it away, I'm
sending it out to see if anybody cares.

Note that we could avoid the final division by instead multiplying
"decimal" with 0.1 rather than multiplying by 10 (and switching the sign
test over), but that's a fundamentally inexact operation in binary floatig
point, so doing the "multiply by tens for decimals" ends up keeping
everything exact as long as possible.

For our use, we probably really don't care, but whatever. End result: this
should not only speed things up immeasurably, it *might* also make things
more precise at a level that we really don't care about :^p

I'm really selling this piece of crap, aren't I?

f3c84ccf75 Math is hard. Let's go shopping.
Alternatively, we could use fabs() to determine the absolute value of

The author of commit b6a30dcdd3 ("Improve floating point equality

23baf20f56 Use "rint()" instead of rounding manually with "+ 0.5"
rint() is "round to nearest integer", and does a better job than +0.5
(followed by the implicit truncation inherent in integer casting).  We
already used 'rint()' for values that could be negative (where +0.5 is
actively wrong), let's just make it consistent.

Of course, as is usual for the messy C math functions, it depends on the
current rounding mode.  But the default round-to-nearest is what we want
and use, and the functions that explicitly always round to nearest
aren't standard enough to worry about.
