Patch for new DW_OP

[Tambay, Pallavi]

Hi,

This patch adds the following dwarf operation as a PGI
(STMicroelectronics) extension.
Operation: DW_OP_PGI_omp_thread_num
Code: 0xf8
No. of operands: 0
Description:
The DW_OP_PGI_omp_thread_num operation pushes the thread number for the
current thread 
as it would be returned by the standard OpenMP library function
omp_get_thread_num().  
The "current thread" is the thread for which the expression is being
evaluated.
