Toma Tabacu 7bc44dcb0c [mips] [IAS] Fix parsing of memory offset expressions with parenthesis depth >1.
Summary:
In an expression such as "(((a+b)+c)+d)", parseParenExpression() would only parse the "a+b)+c", which would result in an error later on in the parser.
This means that we can only parse one level of inner parentheses.

In order to fix this, I added a new function called parseParenExprOfDepth(), which parses a specified number of trailing parenthesis expressions
(except for the outermost parenthesis), and changed MipsAsmParser to use it in parseMemOffset instead of parseParenExpression().

Jack Carter b5cf5909ac Mips assembler: Enable handling of nested expressions
This patch allows the Mips assembler to parse and emit nested 
expressions as instruction operands. It also extends the 
expansion of memory instructions when an offset is given as 
an expression.
