Daniel Sanders 2469f62e81 [mips][ias] Fix all the hacks related to MIPS-specific unary operators (%hi/%lo/%gp_rel/etc.). ... Summary: They are now lexed as a single token on targets where MCAsmInfo::HasMipsExpressions is true and then parsed in a similar way to the '~' operator as part of MCExpr::parseExpression. As a result: * expressions and immediates no longer have different parsing rules. The difference is now solely down to whether evaluateAsAbsolute() succeeds. * %hi(%neg(%gp_rel(x))) are no longer parsed as a single operator and decomposed into the three MipsMCExpr nodes. They are parsed directly as three MipsMCExpr nodes. * parseMemOperand no longer needs to eat all the surrounding parenthesis to get at the outermost operator to make this work * %hi(%neg(%gp_rel(x))) and %lo(%neg(%gp_rel(x))) are no longer the only 3-in-1 relocs that parse for N64. They're still the only combinations that are permitted in relocatable expressions though. Fixing that should be a later patch. * We no longer need to list all the tokens that can occur as the first token of an expression or immediate. test/MC/Mips/expr1.s: This change also prevents the incorrect lowering of %lo(2*4)+foo to %lo(8+foo) which is not an equivalent expression (the difference is whether foo is truncated to 16-bit or not) and the test has been updated to account for the macro expansion the correct expression requires.
