Bill Schmidt 451499f02d This patch is in preparation for adding medium code model support to the 
PPC64 target.  The five tests modified herein test code generation that is
sensitive to the code model selected.  So I've added -code-model=small to
the RUN commands for each.

Since small code model is the default, this has no effect for now; but this
prepares us for eventually changing the default to medium code model for PPC64.

Test changes verified with small and medium code model as default on
powerpc64-unknown-linux-gnu.  All tests continue to pass.

TLS symbols on PowerPC using the integrated assembler.

Adhemerval Zanella f2aceda854 Initial TOC support for PowerPC64 object creation 
This patch adds initial PPC64 TOC MC object creation using the small mcmodel
(a single 64K TOC) adding the some TOC relocations (R_PPC64_TOC,
R_PPC64_TOC16, and R_PPC64_TOC16DS).

The addition of 'undefinedExplicitRelSym' hook on 'MCELFObjectTargetWriter'
is meant to avoid the creation of an unreferenced ".TOC." symbol (used in
the .odp creation) as well to set the R_PPC64_TOC relocation target as the
temporary ".TOC." symbol. On PPC64 ABI, the R_PPC64_TOC relocation should
not point to any symbol.
