917aa35f8f implications of stricter type equality: 
if both types are named, they must be
the same type (arising from the same
declaration).

b5e212ffdd 6g: error messages 
replace "shape error across CALL" with more information.

	a int, b int
	int
x.go:10: assignment count mismatch: 3 = 2
x.go:12: too many arguments to RETURN
	[no arguments expected]
	int, int, int

also leave type alone after conversion failure,
for later errors:

bug049.go:6: cannot convert nil constant to string
bug049.go:6: illegal types for operand: EQ
	string
	nil		# this used to be blank

TEXT tramp
		MOVQ 8(SP), AX
		ADDQ $40, AX
		MOVQ AX, 8(SP)
		JMP oldfunc

	is now

	TEXT tramp
		ADDQ $40, 8(SP)
		JMP oldfunc

	and if s/40/0/, then it simplifies to

	TEXT tramp
		JMP oldfunc

	(the tramp is still needed to satisfy
	symbol references from other object files)

9cba9c8890 6l: eliminate dead code, not just the symbols 
editing the firstp list was ineffective,
because follow rebuilds it from the textp list.

the symbols for dead code were being dropped
from the binary but the code was all still there.

text for fmt.Printf("hello, world\n") drops
from 143945 to 128650.

It now exports a Var interface (anyone can export their own custom var types now), so users need to create and manage their own vars and mark them as exportable via the Publish function. They are exposed via /debug/vars.
