[Mesa3d-dev] minor updates to asm code

[Brian P. <br...@pr...>]

I've moved the definition of the LLBL macro into assyntax.h and
removed it from all .S files.  It also now uses the CONCAT macro.
Then I removed all spaces from all invocations of that macro.
I.e. LLBL( foo ) becomes LLBL(foo).

I did this to fix problem encountered when building on FreeBSD 3.4
inside the XFree86 X tree.

There shouldn't be any side effects to these changes but I'd
appreciate people updating their sources and testing the changes.
