* Add WSYSCALL() to SYS.h, which creates a system call with an
...
internal name and a weak alias for the name.
* Add a WEAKASM syscall list, and process it.
* Make sysarch() have an internal name (_sysarch()).

Remove -Wa,-Av9a hack from <sys.mk> and relegate it to the places that need
...
it (kernel and libc).
The current version of the gas assembler in the tree (2.11.2) already
defaults to generating object files for "-Av9 -64", supporting V9
instructions in ELF64 object format. "-Av9a" is only needed for specific
parts of the NetBSD base sources, and not for all third-party code.

Make __dtoul() actually DTRT. The calling convention was totally wrong, and
...
the `big' value should be 2^63, not 2^31.
Also, nuke __fixunsdfsi(), since this is never output by the sparc64 compiler.

Just use a store/load pair to get the pattern into the FP reg. This eliminates
...
a bunch of cruft and avoids using a v9a instruction.
In addition, eliminate 8 of the fmovda's, which we are not using the result of
anyway.
Net result is that this should be faster in all cases.
