XCore: XCoreLowerThreadLocal improvements

[Robert Lytton]

Hi,

Here is a patch that fixes a bug in the XCore target.
The XCoreLowerThreadLocal tries to initialise globals which have no initializer.

I have also added handling of const expressions containing thread local variables
These need to be replaced with instructions, as the thread ID is used to access the thread local variable.

Robert
