perf tools: regs_query_register_offset() infrastructure
...
regs_query_register_offset() is a helper function which converts
register name like "%rax" to offset of a register in 'struct pt_regs',
which is required by BPF prologue generator.
PERF_HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET indicates an architecture
supports converting name of a register to its offset in 'struct
pt_regs'.
HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET is introduced as the corresponding
CFLAGS of PERF_HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET.

perf: Move arch specific code into separate arch directory
...
The perf userspace tool included some architecture specific code to map
registers from the DWARF register number into the names used by the regs
and stack access API.
This moves the architecture specific code out into a separate
arch/x86 directory along with the infrastructure required to use it.
