 - Also, cleaned up some magic constants while in the area.

2. Fixed EmitLocalCommonSymbol for ELF (Yes, they exist. :)
   Test added.

With this we don't need the EffectiveSize field anymore. Without that field
LayoutFragment only updates offsets and we don't need to invalidate the
current fragment when it is relaxed (only the ones following it).

This is also a very small improvement in the accuracy of the layout info as
we now use the after relaxation size immediately.

Since we now don't update addresses so early, we might relax a bit more than
we need to. This is simillar to the issue in PR8467.

Fix an issue in some Thumb fixups, where the effective PC address needs to be 4-byte aligned when calculating
the offset.  Add a new fixup flag to represent this, and use it for the one fixups that I have a testcase for needing
this.  It's quite likely that the other Thumb fixups will need this too, and to have their fixup encoding logic
adjusted accordingly.

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
