[mips] Correct testcase for .set at=$reg and emit the new warnings for numeric registers too. Summary: Remove the XFAIL added in my previous commit and correct the test such that it correctly tests the expansion of the assembler temporary. Also added a test to check that $at is always $1 when written by the user. Corrected the new assembler temporary warnings so that they are emitted for numeric registers too.

[mips] [IAS] Improve warning for using AT with .set noat. Summary: Changed the warning message to show the current value of $at, similar to what clang does for typedef's, and renamed warnIfAssemblerTemporary to a more descriptive name. I also changed the type of variables which store registers from int to unsigned, updated the relevant test and tried to make the related comments clearer.

# Check that the assembler can handle the documented syntax for ".set at" and
# will set the correct value for $at.
# Note that writing $at is always the same as writing $1.

[mips] Improve support for the .set at/noat assembler directives. Summary: Made the following changes: Added calls to emitDirectiveSetNoAt() and emitDirectiveSetAt(). Added special emit function for .set at=$reg, emitDirectiveSetAtWithArg(unsigned RegNo). Improved parsing error checks for .set at. Refactored parser code for .set at. Improved testing of both directives. Improved code readability and comments.
