[cff] Implement in-house power of 10 
A minimal power only for natural numbers exponents of ten, for portability.

Found the idea in Tcl/Tk but wrote it myself after weeks and it turned out
being a different implementation, reverse direction, constexpr, etc.

7eafe94705 Revert "[array] Add chop()" 
This reverts commit 545fe9d9f0.

Breaks gcc 4.8 and MSVC all versions.

Will add hb_chop() that works on all iterators instead.

545fe9d9f0 [array] Add chop() 
Takes n, and returns iterator of iterators that contain up to
n items each.  Basically cuts the array into subarrays of size n.
The last sub-array might contain fewer.

Ideally this should become a generic iter tool, not array-specific,
so we can use it in GPOS to chop a value matrix into rows and elements.

c72589f13f [iter] Change item_size to get_item_size() 
By moving access to hb_static_size(Type) into a function instead of
a class-const, we can refer to iter types of incomplete types, which
come handy when a method of hb_array_t wants to return iterator
of hb_array_t.  That kind of stuff.   Next commit needs this to
build on clang...

38f95baf6b [subset] in SingleSubst subsetting, check for substitute in glyphset
