Fangrui Song f55e9a2d2e [PPC64] Set the number of relocations processed for R_PPC64_TLS[GL]D to 2 
Summary:
R_PPC64_TLSGD and R_PPC64_TLSLD are used as markers on TLS code sequences. After GD-to-IE or GD-to-LE relaxation, the next relocation R_PPC64_REL24 should be skipped to not create a false dependency on __tls_get_addr. When linking statically, the false dependency may cause an "undefined symbol: __tls_get_addr" error.

R_PPC64_GOT_TLSGD16_HA
R_PPC64_GOT_TLSGD16_LO
R_PPC64_TLSGD R_TLSDESC_CALL
R_PPC64_REL24 __tls_get_addr

Benchmarking

In order to make sure various developers can evaluate patches over the same tests, we create a collection of self contained programs.
