Petr Hosek 39b3c41b65 [InstrProfiling] Use !associated metadata for counters, data and values 
The !associated metadata may be attached to a global object declaration
with a single argument that references another global object. This
metadata prevents discarding of the global object in linker GC unless
the referenced object is also discarded.

Furthermore, when a function symbol is discarded by the linker, setting
up !associated metadata allows linker to discard counters, data and
values associated with that function symbol. This is not possible today
because there's metadata to guide the linker. This approach is also used
by other instrumentations like sanitizers.

Note that !associated metadata is only supported by ELF, it does not have
any effect on non-ELF targets.
