38d8be1ad8 CodeGen: Stick constant pool entries in COMDAT sections for WinCOFF
COFF lacks a feature that other object file formats support: mergeable
sections.

To work around this, MSVC sticks constant pool entries in special COMDAT
sections so that each constant is in it's own section.  This permits
unused constants to be dropped and it also allows duplicate constants in
different translation units to get merged together.

This fixes PR20262.

4dff258bfb The LIT tests below do not specify the exact cpu model and fail on AVX2 machines, because we select different instructions such as vbroadcast, new shuffles, etc.

41cedd740d Revert r149110 and add a testcase that was crashing since that revision.
Unfortunately I also had to disable constant-pool-sharing.ll the code it tests has been
updated to use the IL logic.

83f6120c9a Allow constants of different types to share constant pool entries
if they have compatible encodings.
