multilib build and installs.
Summary:
This requires introducing a generated header to encapsulate the
LLVM_LIBDIR_SUFFIX value from the build system and push it into the go
code. From there, I've adjusted the gllgo code to systematically use
this rather than a raw "lib". This requires some awkwardness as one of
the flags *must* be "lib"-relative for compatibility with how gccgo
works. For that flag, we use ".." to back up a directory and then go
into the proper lib directory.

Patch by Andrew Wilkins!
canAvoidElementLoad and canAvoidLoad were incorrectly
eliding loads when an index expression is used as an
another array index expression. This led to a panic.

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().
