Daniel Sanders c141b331b9 [mips] Fix assembler temporary expansion and add associated warnings about the use of $at. ... Summary: The assembler temporary is normally $at ($1) but can be reassigned using '.set at=$reg'. Regardless of which register is nominated as the assembler temporary, $at remains $1 when written by the user. Adds warnings under the following conditions: * The register nominated as the assembler temporary is used by the user. * '.set noat' is in effect and $at is used by the user. Both of these only work for named registers. I have a follow up commit that makes it work for numeric registers as well. XFAIL set-at-directive.s since it incorrectly tests that $at is redefined by '.set at=$reg'. Testcases will follow in a separate commit.
