This patch implements parsing of mips FCC register operands. The example instructions have been added to test files.

beq $2, $zero, $L1 => beqz $2, $L1

parsing methods.

This removes the need to store the asm variant in each row of the single table that existed before. Shaves ~16K off the size of X86AsmParser.o.

llvm-svn: 187026

Enable parsing all 32 floating point control registers $0-31 and stop trying to
parse floating point condition code register $fcc0. Also, return ParseFail if
the operand being parsed is not in the expected format.

MatchTable.

This patch extends mips register parsing methods to allow indexed register parsing. The corresponding test cases are added to the patch.

This patch checks for valid mnemonics at the beginning of parseInstruction method, thus giving the user the right error message for non-existing instructions.

 This patch represents Mips utilization of r186388 code that alows asm matcher to emit mnemonics contain '.' characters. This makes asm parser code simpler and more efficient.
