Summary:
This macro is needed to prevent test/CodeGen/Mips/2008-08-01-AsmInline.ll from
failing after the integrated assembler is enabled by default.

Summary:
- Signed 16-bit should have priority over unsigned.
- For la, unsigned 16-bit must use ori+addu rather than directly use ori.
- Correct tests on 32-bit immediates with 64-bit predicates by
sign-extending the immediate beforehand. For example, isInt<16>(0xffff8000)
should be true and use addiu.
Also split li/la testing into separate files due to their size.

Summary:
This only adds support for ULW of an immediate address with/without a source register.
It does not include support for ULW of the address of a symbol.

Summary:
For some branches, GAS accepts an immediate instead of the 2nd register operand.
We only implement this for BNE and BEQ for now. Other branch instructions can be added later, if needed.

Summary: A side-effect of this is that LA gains proper handling of unsigned and positive signed 16-bit immediates and more accurate error messages.

Summary:
LI should never accept immediates larger than 32 bits.
The additional Is32BitImm boolean also paves the way for unifying the functionality that LA and LI have in common.

Summary: Changed error messages to be more informative and to resemble other clang/llvm error messages (first letter is lower case, no ending punctuation) and updated corresponding tests.

Patch by David Chisnall
His work was sponsored by: DARPA, AFRL
Some small modifications to the original patch: we now error if
it's not possible to expand an instruction (mips-expansions-bad.s has some
examples). Added some comments to the expansions.
