This CL removes the remaining visible uses of the "architecture letter" concept.
(They are no longer in tool names nor in source directory names.)
Because the architecture letter concept is now gone, delete GOCHAR
from "go env" output, and change go/build.ArchChar to return an
error always.
The architecture letter is still used in the compiler and linker sources
as a clumsy architecture enumeration, but that use is not visible to
Go users and can be cleaned up separately.

Overall:
- toolchain in Go
- new GC
+- go tool asm, go tool compile, go tool link
+- default output files changed: now file.o and a.out
Language:
- permit omission of key type in map composite literals where key is a composite literal (https://golang.org/cl/2591)
