Fixed bug in delay_cycles_32x insn.
There is a bug in the insn that generates the delay loop for the instrinsic
__delay_cycles() function. This bug is noticeable under some circumstances,
where the target is an MSP430X core and the cycle count is representable as a
32 bit number. This bug results in the corruption of r14 in a function that
utilizes the instrinsic under the above conditions. A bug report has been filed
at [1] with a patch submitted. The same patch is applied here. Although it is
improbable that this instrinsic is used in newlib, it is suggested to
recompile it just in case.
