Peter Collingbourne 08b4728f51 irgen: Create functions instead of global variables for builtin hash and equal algorithms.
These are in fact functions, and have function type, so it is invalid
to represent them using global variables.

Andrew Wilkins 6436a4abd7 [llgo] Roll gofrontend forward
Switch gofrontend to using go.googlesource.com, and
update to 81eb6a3f425b2158c67ee32c0cc973a72ce9d6be.

There are various changes required to update to the
go 1.5 runtime:

typemap.go is changed to accommodate the change in representation for equal/hash algorithms, and the removal of the zero value/type.
CMakeLists.txt is updated to add the build tree to the package search path, so internal packages, which are not installed, are found.
various files changes due to removal of __go_new_nopointers; the same change as in D11863, but with NoUnwindAttribute added to the added runtime functions which are called with "callOnly".
minor cleanups in ssa.go while investigating issues with unwinding/panic handling.

Peter Collingbourne 93c73ebcbd Roll gofrontend to a6e10414311a
This takes us to Go 1.4. Also includes a couple of changes to the test
suite, both in the runtime package:

- Disable TestSetPanicOnFault. We cannot support this scenario at all,
  due to LLVM's lack of non-call exceptions.

- Tweak TestFinalizerType. This test only passes with two GC runs.

Peter Collingbourne 56109b78c7 Roll gotools to 47f2109c.
At the same time, perform a number of simplifications:

- Rename go.tools directory to gotools.

- Import only the go directory; all required Go analysis code and
  its dependencies have now been moved to this directory.

Peter Collingbourne 82a260eaaf irgen: introduce ManglePackagePath function
This is useful for clients that need to use llgo's mangling of the package
path to look up a specific function within a given package.

Peter Collingbourne 545e7276a8 Use the object's package to mangle method names, rather than the receiver's package
If we use the receiver's package, we can end up with identical manglings
for different functions. Consider:

package p
type U struct{}
func (U) f()

package q
import "p"
type T struct { p.U }
func (T) f()

The method set of *T has two synthetic methods named (*T).f(); one forwards to
(T).f(), and the other to (U).f(). Previously, we were distinguishing them
by the receiver's package, and in this case because both methods have the
same receiver, they received the same name.

The methods are correctly distinguished by the package owning the identifier
"f", which is available via f.Object().Pkg().
