This patch fixes the R_AARCH64_TLSLE_ADD_TPREL_HI12 and R_AARCH64_TLSLE_ADD_TPREL_LO12_NC handling by using the correct offset by using the target layout along with aarch64 alignments requirements. It fixes the TLS test-suite SingleSource failures for aarch64: * SingleSource/UnitTests/Threads/2010-12-08-tls.execution_time * SingleSource/UnitTests/Threads/tls.execution_time llvm-svn: 238258
