7e69c90ade runtime: Add some missing runtime· prefixes to ARM asm code.

68b4255a96 runtime: ,s/[a-zA-Z0-9_]+/runtime·&/g, almost
Prefix all external symbols in runtime by runtime·,
to avoid conflicts with possible symbols of the same
name in linked-in C libraries.  The obvious conflicts
are printf, malloc, and free, but hide everything to
avoid future pain.

The symbols left alone are:

	** known to cgo **
	_cgo_free
	_cgo_malloc
	libcgo_thread_start
	initcgo
	ncgocall

	** known to linker **
	_rt0_$GOARCH
	_rt0_$GOARCH_$GOOS
	text
	etext
	data
	end
	pclntab
	epclntab
	symtab
	esymtab

	** known to C compiler **
	_divv
	_modv
	_div64by32
	etc (arch specific)

Tested on darwin/386, darwin/amd64, linux/386, linux/amd64.

Built (but not tested) for freebsd/386, freebsd/amd64, linux/arm, windows/386.

df88fc6109 arm: bugfixes and syscall
- integer divide by zero raises panic
- float comparisons involving NaNs work
- syscall interface actually handles return
  values and errno correctly.

23c0aa3916 runtime/arm: fix build
Import _mulv from Inferno again, change R9 to R2.
Not sure what the other differences were for, but
they weren't working.

26e846429d support for printing floats:
fmt.Printf("float32 %f\n", float32(1234.56789))
fmt.Printf("float64 %f\n", float64(1234.56789))
->
float32 1234.567871
float64 1234.567890

this is a snapshot. extended instruction support, corner cases
and fixes coming in subseuent cls.

46e392e01c changed 5c calling convention to use stack exclusively for in
params. a number of fixes to assembly routines that assumed R0
had the first arg. one stack offset fix, arm pushes the link
register on stack top.

go/test: passes 65% (235/364) tests
