SUMMARY:
in the xcoff, if the number of relocation entries or line number entries is
overflow(large than or equal 65535) , there will be overflow section for it.
The interpret of overflow section is different with generic section header,
the patch implement parsing the overflow section.

Summary:
According the the XCOFF document,
If
Then
XTY_SD
x_scnlen contains the csect length.
XTY_LD
x_scnlen contains the symbol table index of the containing csect.
XTY_CM
x_scnlen contains the csect length.
XTY_ER
x_scnlen contains 0.
Change the SectionLen member name to SectionOrLength is more reasonable.

Summary:
This patch implements main entry and auxiliary entries of symbol table generation for llvm-readobj on AIX.
The source code of aix_xcoff_xlc_test8.o (compile with xlc) is:
-bash-4.2$ cat test8.c
extern int i;
extern int TestforXcoff;
extern int fun(int i);
static int static_i;
char* p="abcd";
int fun1(int j) {
static_i++;
j++;
j=j+*p;
return j;
}
int main() {
i++;
fun(i);
return fun1(i);
}

Adds a readobj dumper for 32-bit and 64-bit section header tables, and extend
support for the file-header dumping to include 64-bit object files. Also
refactors the binary file parsing to be done in a helper function in an attempt
to cleanup error handeling.

Summary:
This patch implement parsing symbol table for xcoffobjfile and
output as yaml format. Parsing auxiliary entries of a symbol
will be in a separate patch.
The XCOFF object file (aix_xcoff.o) used in the test comes from
-bash-4.2$ cat test.c
extern int i;
extern int TestforXcoff;
int main()
{
i++;
TestforXcoff--;
}

Patch adds support for dumping of file headers with llvm-readobj. XCOFF
object files are added to test dumping a well formed file, and dumping
both negative timestamps and negative symbol counts, both of which are
allowed in the XCOFF definition.
