in a .6 file, an export line
//ffi T localfib remotefib remote.so
means the dynamic linker should initialize
localfib, always a pointer, to the address of
remotefib, either text (T) or data (D) after
loading remote.so.
the C compiler will generate an export section
when given the pragmas
#pragma package fib
#pragma ffi T localfib remotefib remote.so
needing #pragma package is a bit of a kludge
and hopefully could go away later.
this is just the 6 tool chain support.
other architectures will happen once 6 settles down.
code using this to do FFI is in a later CL.

6g's error for I4 is not quite accurate
(it calls I4 a non-interface) but also
not a crash or infinite loop.

message with the full path of the errchk script. Catch that
by wrapping the if statement which invokes the compiler in a
subshell. Use the $TMPOUT file as a flag to let the main
shell know whether the subshell ran. Since the compiler
stdout and stderr are redirected, if the if statement produces
any output, then the compiler crashed, and we report that.

- fixed a number of places where we tried to allocate 64bit
regs. added honeypot in regalloc to catch these in the future.
- implemented quad copying in sgen
- cgen64.c, add, mul
- clearfat done
- D_REGREG output from 5g (linker already knew about them)
- gmove done
- optoas almost done, last bit probably not needed
- D_SHIFT support in list.c

looked up in a different namespace if the composite literal

introduced explicit "data" symbol instead of etext
to mark beginning of data, so that using larger
alignment (i.e. 4MB like GNU loader) doesn't
confuse garbage collector.
split dodata into dodata and dobss in preparation
for putting the dynamic data + headers in the data
segment instead of stuffed at the beginning of the binary.
