[gdb] Add debug_{exp,val}linaro-local/ci/tcwg_kernel/llvm-master-arm-next-allmodconfiglinaro-local/ci/tcwg_kernel/llvm-master-aarch64-lts-allmodconfiglinaro-local/ci/tcwg_kernel/gnu-master-arm-lts-allyesconfiglinaro-local/ci/tcwg_kernel/gnu-master-aarch64-stable-allnoconfiglinaro-local/ci/tcwg_bmk_llvm_fx/llvm-master-aarch64-spec2k6-O2

When debugging cc1 I heavily rely on simple one-parameter debug functions
that allow me to inspect a variable of a common type, like:
- debug_generic_expr
- debug_gimple_stmt
- debug_rtx
and I miss similar functions in gdb.

Add functions to dump variables of types 'value' and 'expression':
- debug_exp, and
- debug_val.

Tested on x86_64-linux, by breaking on varobj_create, and doing:
...
(gdb) call debug_exp (var->root->exp.get ())
&"Operation: OP_VAR_VALUE\n"
&" Block symbol:\n"
&"  Symbol: aaa\n"
&"  Block: 0x2d064f0\n"
(gdb)
...
and:
...
(gdb) call debug_val (value)
&"5"
(gdb)
...
