Move wrappers to libm-compat-calls-auto
This commit moves one step towards the deprecation of wrappers that
use _LIB_VERSION / matherr / __kernel_standard functionality, by
adding the suffix '_compat' to their filenames and adjusting Makefiles
and #includes accordingly.
New template wrappers that do not use such functionality will be added
by future patches and will be first used by the float128 wrappers.
