Simon Dardis 3aa8a90eff [mips] dla expansion without the at register
Previously only the superscalar scheduled expansion of the dla macro for
MIPS64 was implemented. If assembler temporary register is not available
and the optional source register is not the destination register, synthesize
the address using the naive solution of adds and shifts.

This partially resolves PR/30383.

Thanks to Sean Bruno for reporting the issue!

Daniel Sanders d5a89418c5 [mips] Changed the way symbols are handled in dla and la instructions to allow simple expressions.
Summary:
An instruction like "(d)la $5, symbol+8" previously would have crashed the
assembler as it contains an expression. This is now fixed.
A few tests cases have also been changed to reflect these changes, however
these should only be syntax changes. Some new test cases have also been
added.

Patch by Scott Egerton.

Daniel Sanders a39ef1c68f [mips] [IAS] Add support for the DLA pseudo-instruction and fix problems with DLI
Summary: It is the same as LA, except that it can also load 64-bit addresses and it only works on 64-bit MIPS architectures.
