[PATCH] remove nested functions from elf/dl-load.c

[Konstantin Serebryany]

Hi,

Please review the patch that removes nested functions from elf/dl-load.c
I had to pack 4 parameters into a struct, just like with hack_digit in
stdio-common/printf_fp.c recently. With this patch the generated code
for _dl_rtld_di_serinfo is ~8 instructions
longer than in trunk (larger function prologue/epilogue) and add_path
is 2 instructions longer.

No regressions in 'make check' on x86_64-linux-gnu (Ubuntu 14.04)

        * elf/dl-load.c
        (add_path): New function broken out of _dl_rtld_di_serinfo.
        (_dl_rtld_di_serinfo): Remove a nested function. Update call sites.
