Ayke van Laethem 8cbfbcae5a build: avoid sharing GlobalValues between build instances

This happens with `tinygo test` for example when testing multiple
packages at the same time. I found this because the compiler crashed in
`make tinygo-test-fast`:

    fatal error: concurrent map writes
    fatal error: concurrent map read and map write

    goroutine 15 [running]:
    github.com/tinygo-org/tinygo/builder.Build({0x40002d0be0, 0xa}, {0x0, 0x0}, {0x4000398048, 0x14}, 0x40003b0000)

My solution is essentially to copy the map over instead of modifying it
directly.

I've also moved the code up a little, because I think that's a more
sensible place (out of the way of the whole package compile logic).
