Add convenient helper for checking whether global is weak in linker sense

having weak or linkonce or common or extweak LLVM linkage.

Factor code to copy global value attributes like
...
the section or the visibility from one global
value to another: copyAttributesFrom. This is
particularly useful for duplicating functions:
previously this was done by explicitly copying
each attribute in turn at each place where a
new function was created out of an old one, with
the result that obscure attributes were regularly
forgotten (like the collector or the section).
Hopefully now everything is uniform and nothing
is forgotten.

Add CommonLinkage; currently tentative definitions
...
are represented as "weak", but there are subtle differences
in some cases on Darwin, so we need both. The intent
is that "common" will behave identically to "weak" unless
somebody changes their target to do something else.
No functional change as yet.

merge several fields in GlobalValue to use the same word, move CallingConv

field into SubclassData in Value. This shrinks GlobalVAlue from 48->40
bytes, Function from 88->76, and GlobalVariable from 76->68. This trims

functions.

exprs hanging off a global, even if the global is not otherwise dead. This
