[mips] Fix li/la differences between IAS and GAS. 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.

[mips][ias] fix li macro when values are negated with ~ The integrated assembler evaluates the expressions such as ~0x80000000 to 0xffffffff7fffffff early in the parsing process. This patch adds compatibility with gas so that li loads the expected value (0x7fffffff) in those cases. This only occurs iff all the upper 32bits are set and maintains existing checks by not truncating the result down to 32 bits if any of the the upper bits are not set.
