PR 19051: support of inferior call with gnu vector support on ARM
This patch teaches GDB to support gnu vector in inferior calls. As a
result, fails in gdb.base/gnu_vector.exp are fixed. The calling
convention of gnu vector isn't documented in the AAPCS, because it
is the GCC extension. I checked the gcc/config/arm/arm.c, understand
how GCC pass arguments and return values, and do the same in GDB side.
The patch is tested with both hard float and soft float on arm-linux.
