IR file demonstrating the bug.

If you compile the attached tls.ll with these commands:

llc -filetype=obj tls.ll
gcc -m64 -g tls.o

then it results in the following error message:

/usr/bin/ld: t.o(.debug_info+0x39): R_PPC64_ADDR64 used with TLS symbol
_D6tlsrel3ptrPv

The .ll file is reduced from a larger file generated by LDC. The error does not
occur if not Dwarf debug info is generated.
