This adds support for TLS CALL relocations. TLS CALL relocations are used to indicate to the linker to generate appropriate entries to resolve TLS references via an appropriate function invocation (e.g. __tls_get_addr(PLT)). In order to accomodate the linker relaxation of the TLS access model for the references (GD/LD -> IE, IE -> LE), the relocation addend must be incomplete. This requires that the partial inplace value is also incomplete (i.e. 0). We simply avoid the offset value calculation at the time of the fixup adjustment in the ARM assembler backend. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200446 91177308-0d34-0410-b5e6-96231b3b80d8
