instcombine xform to exercise this.
Nothing forms exact udivs yet though. This is progress on PR8862

First step in fixing PR8927:2011-01-08T16:42:36ZRafael Espindolarafael.espindola@gmail.com2011-01-08T16:42:36Zurn:sha1:bea4626f93c830e31f82cc947df28fdae583cd09
Add a unnamed_addr bit to global variables and functions. This will be used
to indicate that the address is not significant and therefore the constant
or function can be merged with others.
If an optimization pass can show that an address is not used, it can set this.
Examples of things that can have this set by the FE are globals created to
hold string literals and C++ constructors.
Adding unnamed_addr to a non-const global should have no effect unless
an optimization can transform that global into a constant.
Aliases are not allowed to have unnamed_addr since I couldn't figure
out any use for it.

Discard metadata produced by LLVM 2.7. The value enumeration it used2010-09-09T23:12:39ZDan Gohmangohman@apple.com2010-09-09T23:12:39Zurn:sha1:70c2fc0823bcc3970fdebf18ba69449d7822af86
is different from what the code now uses in a two ways: NamedMDNodes
were considered Values and included in the numbering, and the
function-local metadata counter wasn't reset between functions.
The later problem breaks lazy deserialization, so instead of trying
to emulate the old numbering, just drop the old metadata. The only
in-tree use case is debug info with LTO, where the QOI loss is
considered acceptable.
