The ARM TLS relocations are placed on literal data and not the
code-sequence, it is therefore not possible to implement the relaxTls*
functions. This change updates handleMipsTlsRelocation() to
handleNoRelaxTlsRelocation() and incorporates ARM as well as Mips.
The ARM support in handleNoRelaxTlsRelocation() currently needs to ouput
the module index dynamic relocation in all cases as it is relying on the
dynamic linker to set the module index in the got.
Should address PR30218
