Reorganise machmode.h headers

This patch splits the auto-generated inline functions out of
insn-modes.h and puts them in a new header file, insn-modes-inline.h.
It also makes coretypes.h include these files directly, rather than
indirectly via machmode.h.  This in turn allows insn-modes-inline.h
and machmode.h to come later in the include list, after wide-int.h.
This is useful for later patches.

insn-modes.h itself still needs to come first, since it provides
configuration information like MAX_BITSIZE_MODE_ANY_INT, which is
used to control the size of a wide_int.

The patch also makes the generator files include machmode.h
via coretypes.h.  Previously they did it by more indirect means.

Finally, the patch makes wide-int-print.h available via coretypes.h
too.  There didn't seem to be any reason to force only the print
routines to be included directly, and it would be painful to extend
that approach to the SVE patches.
