cmd/compile: define func value symbols at declaration This is mostly Russ's https://golang.org/cl/12145 but with some extra fixes to account for the fact that function declarations without implementations now break shared libraries, and including my test case. Fixes #11480. Change-Id: Iabdc2934a0378e5025e4e7affadb535eaef2c8f1 Reviewed-on: https://go-review.googlesource.com/12340 Reviewed-by: Ian Lance Taylor <iant@golang.org>

cmd/link: always read type data for dynimport symbols Consider three shared libraries: libBase.so -- defines a type T lib2.so -- references type T lib3.so -- also references type T, and something from lib2 lib2.so will contain a type symbol for T in its symbol table, but no definition. If, when linking lib3.so the linker reads the symbols from lib2.so before libBase.so, the linker didn't read the type data and later crashed. The fix is trivial but the test change is a bit messy because the order the linker reads the shared libraries in ends up depending on the order of the import statements in the file so I had to rename one of the test packages so that gofmt doesn't fix the test by accident...
