CL 301650 adds conversion from slice to array ptr. The conversion
expression may appear as argument to a function call, so it will be
tested by mayCall. But ir.OSLICE2ARRPTR op is not handled by mayCall,
causes the compiler crashes.

callMethod previously assumed erroneously that between the "value" and
"method" ABIs (that is, the ABI the caller is following to call this
method value and the actual ABI of the method), it could never happen
that an argument passed on the stack in the former could be passed in
registers in the latter. The cited reason was that the latter always
uses strictly more registers.
However, there are situations where the value ABI could pass a value on
the stack, but later is passed in a register. For instance, if the
receiver pushes a value passed in registers that uses multiple registers
to be passed on the stack, later arguments which were passed on the
stack may now be passed in registers.
This change fixes callMethod to no longer makes this assumption, and
handles the stack-to-register translation explicitly.
Fixes#46696.

The compiler machinery that generates "map.zero" symbols marks them as
RODATA and DUPOK, which is problematic when a given application has
multiple map zero symbols (from different packages) with varying
sizes: the dupok path in the loader assumes that if two symbols have
the same name, it is safe to pick any of the versions. In the case of
map.zero, the link needs to select the largest symbol, not an
arbitrary sym.
To fix this problem, mark map.zero symbols as content-addressable,
since the loader's content addressability processing path already
supports selection of the larger symbol in cases where there are dups.
