Language mappings to machine types table misses capabilities for AAPCS

[mmalcomson]

I believe that AAPCS includes the hybrid model in the aapcs64-morello document. At the bottom of this document there is a table of C/C++ types to machine types.

The entries with __capability should be capability machine types in AAPCS.
