a0871e7927 ARM/MC/ELF TPsoft is now a proper pseudo inst. 
Added test to check bl __aeabi_read_tp gets emitted properly for ELF/ASM
as well as ELF/OBJ (including fixup)

Also added support for ELF::R_ARM_TLS_IE32

06d65f5156 Fix a bad prologue / epilogue codegen bug where the compiler would emit illegal 
vpush instructions to save / restore VFP / NEON registers like this:
vpush {d8,d10,d11}
vpop {d8,d10,d11}

vpush and vpop do not allow gaps in the register list.
