1. Added a new option bit mode  -X for llvm-ar.

In AIX OS  , there is a bit mode option -X for ar command. 
please see the "-X mode" part of  https://www.ibm.com/docs/ko/aix/7.1?topic=ar-command

Specifies the type of object file ar should examine. The mode must be one of the following:
**32**
Processes only 32-bit object files
**64**
Processes only 64-bit object files
**32_64**
Processes both 32-bit and 64-bit object files
**any**
Processes all of the supported object files.

The default is to process 32-bit object files (ignore 64-bit objects). The mode can also be set with the OBJECT_MODE environment variable. For example, OBJECT_MODE=64 causes ar to process any 64-bit objects and ignore 32-bit objects. The -X flag overrides the OBJECT_MODE variable.

2.before adding the new option -X, the default behaviors of llvm-ar  like -Xany,  but after the adding the new option -X, the default behaviors of llvm-ar  change to -X32 ,in order to   let some test cases which has 32bit and 64bit object file in the same llvm-ar command, we need to add the  "export OBJECT_MODE=any" into test case to change the default behaviors of llvm-ar's object mode.
