0884836277 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.

f894199a14 [mips] Trap on integer division by zero. 
By default, a teq instruction is inserted after integer divide. No divide-by-zero
checks are performed if option "-mnocheck-zero-division" is used.

standard mips32) arithmetic 32-bit instructions.

9d577c8614 Implement methods that enable expansion of load immediate 
macro instruction (li) in the assembler.

We have identified three possible expansions depending on 
the size of immediate operand:
  1) for 0 ≤ j ≤ 65535.
     li d,j =>
     ori d,$zero,j

  2) for −32768 ≤ j < 0.
     li d,j =>
     addiu d,$zero,j

  3) for any other value of j that is representable as a 32-bit integer.
     li d,j =>
     lui d,hi16(j)
     ori d,d,lo16(j)

All of the above have been implemented in ths patch.

18f3c78092 This patch adds a predicate to existing mips32 and mips64 so that those 
instruction encodings can be excluded during mips16 processing.

This revision fixes the issue raised by Jim Grosbach.

bool hasStandardEncoding() const { return !inMips16Mode(); }

When micromips is added it will be

bool StandardEncoding() const { return !inMips16Mode()&&  !inMicroMipsMode(); }

No additional testing is needed other than to assure that there is no regression
from this patch.
