...to match the new interface between "go test" and the standard testing
package.
Rather than generate SSA code directly, which was tricky and fragile, we
now generate source just as "go test" does, type-check it, and build an
SSA package from it. crawshaw suggested I do this in the very first
version of testmain.go, but at the time I believed it to be infeasible.
The testMainStartBodyHook mechanism has gone away; installations that
needed it can now achieve the same results more easily by overriding the
templates.
Tested with Go 1.6, 1.7 and 1.8.

Allow extra arguments to be passed to the specified gccgo compiler
when it is called in GccgoInstallation.InitFromDriver. This allows
the call to gccgo to be adjusted depending on the build environment.
For example, some build environments require the
'no-canonical-prefixes' option to prevent gccgo from resolving
symlinks when generating relative prefixes.

Supporting user-defined TestMain functions requires that we generate a
"testmain" package for each testable package, rather than a single one
for the entire program. This entails these API changes:
1. (*ssa.Program).{CreateTestMainPackage,FindTests} both now
accept only a single package. Existing clients that pass them
multiple packages must call them from a loop.
2. (*ssa.Program).FindTests returns an additional result, the the
optional TestMain *ssa.Function. Existing clients may discard it.
Also:
- Test the new logic using the SSA interpreter
- add ssautil.MainPackages helper
- callgraph: allow multiple main packages, and analyze them all
- ssadump -run: allow multiple main/test packages, and run each in a new interpreter
- minor simplifications to some callers (e.g. guru)
