consist of multiple named or unnamed items with same type.

Fixes#3456.
This proposal is a reformulation of CL 5987063. This CL resets
the default GOARM value to 6 and allows the use of the VFPv3
optimisation if GOARM=7. Binaries built with this CL in place
will abort if GOARM=7 was used and the target host does not
support VFPv3.

This fixes a problem with ELF tools thinking they know the
format of the symbol table, as we do not use any of the
standard formats for that table.
This change will probably annoy the Plan 9 users, but I
believe there are other incompatibilities already that mean
they have to use a Go-specific nm.
Fixes#3473.

go tool dist env -w is supposed to print a Windows batch file.
Normally Windows will execute batch files without \r before \n,
but issue 3060 reports that if the file ends up containing paths
written in Chinese, Windows 7 cannot execute it without the \r.
So add the \r.
Fixes#3060.

It is enough to load directly the data word and the itab word
from memory, so we save a LEA instruction for each method call,
and allow elimination of some extra temporaries.

Removes an extra LEAL/LEAQ instructions there and usually saves
a useless temporary in the idiom
if err := foo(); err != nil {...}
Generated code is also less involved:
MOVQ err+n(SP), AX
CMPQ AX, $0
(potentially CMPQ n(SP), $0) instead of
LEAQ err+n(SP), AX
CMPQ (AX), $0

The main case where it happens is when evaluating &s[i] without
bounds checking, which usually happens during range loops (i=0).
This allows registerization of the corresponding variables,
saving 16 bytes of stack frame for each such range loop and a
LEAQ instruction.
