Don't merge two constants if we care about the address of both.2011-01-16T17:05:09ZRafael Espindolarafael.espindola@gmail.com2011-01-16T17:05:09Zurn:sha1:d6e5cbc84226ad4a62e8847f1babecf86089d415
This fixes the original testcase in PR8927. It also causes a clang
binary built with a patched clang to increase in size by 0.21%.
We can probably get some of the size back by writing a pass that
detects that a global never has its pointer compared and adds
unnamed_addr to it (maybe extend global opt). It is also possible that
there are some other cases clang could add unnamed_addr to.
I will investigate extending globalopt next.

1. modernize the constantmerge pass, using densemap/smallvector.2010-02-12T18:17:23ZChris Lattnersabre@nondot.org2010-02-12T18:17:23Zurn:sha1:c3b6ffc431bbf01f615c6695a0dc1b9368102cad
2. don't bother trying to merge globals in non-default sections,
doing so is quite dubious at best anyway.
3. fix a bug reported by Arnaud de Grandmaison where we'd try to
merge two globals in different address spaces.
