Constructor is unchanged from ia32 version.  Code size and offsets remain 32-bit
(int).

LGTM if you re-staticize the spare bugger.

I think this one should be static. It's for reusing a buffer between different
assembler instances, to avoid allocating a new one every time.

The declaration in the class definition is static.  The definition does not need
the keyword static, and static means something different if it is used here
(file-scoped visibility).
