During package initialization, the compiler tries to optimize: var A = "foo" var B = A into var A = "foo" var B = "foo" so that we can statically initialize both A and B and skip emitting dynamic initialization code to assign "B = A". However, this isn't safe in the presence of cmd/link's -X flag, which might overwrite an initialized string-typed variable at link time. In particular, if cmd/link changes A's static initialization, it won't know it also needs to change B's static initialization. To address this, this CL disables this optimization for string-typed variables. Fixes #34675.
