libdw: Robustify eh_frame_hdr and encoded-values reading.
Sanity check and keep track of binary_search_table data buffer length.
Add bounds check to encoded value reading. Also fix a bug when reading
the eh_frame header data from an other endian ELF image. Add a testcase
that would fail the new sanity checks because of the endian bug.

backends: Add aarch64 abi_cfi.
Setup initial CIE values for aarch64 for use with dwarf_frame functions.
Register info prefix should be the empty string (not NULL) when not used.
Add an EM_AARCH64 testcase to tests/run-addrcfi.sh to check both issues.

backends: ppc_abi_cfi reg1 use DW_CFA_val_offset not DW_CFA_val_expression.
Register rules using expressions are stored using an offset from the
start of the .eh_frame or .debug_frame ELF section data. Since abi_cfi
rules aren't stored in those ELF sections they should use neither
DW_CFA_expression nor DW_CFA_val_expression. The only backend that used
DW_CFA_val_expression was ppc_cfi.c. It was easier to express the same
rule using DW_CFA_val_offset than to change the code to handle register
rules using expressions. On most architectures this did work by accident.
See the definition of struct dwarf_frame_register value in libdw/cfi.h to
see why. But on ia64 the abi_cfi data and actual frame data were placed
too far apart and caused a crash in tests/run-addrcfi.sh for ppc32.

backends: Hook abi_cfi for arm.
New arm_abi_cfi that defines initial CFA, rules for callee-saved regs,
including VFP ones and return register.
Note the DWARF abi extension for ARM says that "registers intentionally
unused" should also be initialized as if by DW_CFA_same_value. The
example given is "an integer-only function might be included in one
executable file for targets with VFP and another for targets without".
We don't currently do this yet. See the DWARF and calling convention
documents:
DWARF for the ARM Architecture ABI r2.09
http://infocenter.arm.com/help/topic/com.arm.doc.ihi0040b/IHI0040B_aadwarf.pdf
Procedure Call Standard for the ARM Architecture ABI r2.09
http://infocenter.arm.com/help/topic/com.arm.doc.ihi0042e/IHI0042E_aapcs.pdf
Also adds addrcfi arm testcase.

tests: Add run-addrcfi.sh test for libdw cfi dwarf_frame_* functions.
We require architecture backends to implement the ebl abi_cfi hook
to provide the ABI's default CFI program as used by the libdw dwarf cfi
functions. There is the addrcfi test program that prints the return
address, cfa location expression and register states as returned by
various dwarf_cfi_* and dwarf_frame functions. But that has to be run
by hand. The new run-addrcfi.sh tests hooks addrcfi up to some existing
architecture specific test files and known addresses to more easily
(and automaticly) check that the default CFI program is implemented
correctly and to test the libdw cfi frame info functionality.
Only i386 and x86_64 are tested for now since other backends don't have
the abi_cfi hook yet.
