The original analysis of the Go corpus assumed that these
stripped monotonic time. During the design discussion we
decided to try not stripping monotonic time here, but existing
code works better if we do.

The test assumed that passing an unknown option to the Fortran
compiler would cause the compiler to fail. Unfortunately it appears
that some succeed. It's irrelevant to the actual test, which is
verifying that the flag was indeed passed.

Make sure that if we encode an explicit base register, we print it.
That will ensure that if we make an Addr with an auto variable but
a base that isn't SP, then it will be obvious from the disassembly.

This makes a change in the SSA code generated for OpPPC64Xf2i64

The builtin runtime package definitions intentionally diverge from the
actual runtime package's, but this only works as long as they never
overlap.
To make it easier to expand the builtin runtime package, this CL now
loads their definitions into a logically separate "go.runtime"
package. By resetting the package's Prefix field to "runtime", any
references to builtin definitions will still resolve against the real
package runtime.

did not differentiate if an invalid UTF-8 sequence was decoded

of 1 for an invalid sequences. This cl adds a check to correctly
determine the length of bytes needed to advance to the next rune.
