spec2k6 456.hmmer build fail.
one of the errors can be reproduce by the following code:

#include <stdio.h>
#include <stdlib.h>
#include <stdarg.h>

void
Die(char *format, ...)
{
  va_list  argp;
				/* format the error mesg */
  fprintf(stderr, "\nFATAL: ");
  va_start(argp, format);
  vfprintf(stderr, format, argp);
  va_end(argp);
  fprintf(stderr, "\n");
  fflush(stderr);
				/* exit  */
  exit(1);
}

error:

fix issue open64-compiler#35 for WHIRL2llvm
800bc43 
The offset is the distance between the field of struct and the start of struct,
but the parameter just be pushed one time if the parameter just hold one register.
So we need to align down the offset of field to register size.

1. The w2ll will crash if compile the code like that:
```
typedef struct quantum_matrix_struct {
  int rows;
  int cols;
} quantum_matrix;

void
quantum_print_matrix(quantum_matrix m)
{
  int i, j;
  for(i=0; i<m.rows; i++)
  {
    for(j=0; j<m.cols; j++) {
        printf("%d\n", 1);
    }
  }
}
```

2. Error Log:
```
Find_parm_type cannot find
```
