31440e9796 Make libunwind pass C++ exceptions correctly
When libunwind is linked with a C++ program that throws exceptions,
the exception that's thrown is passed in %rax. However, libc's
setcontext clears %rax, causing problems.

This patch implements a setcontext that doesn't clobber rax.

TBD: Add dwarf CFI annotations

1fdb08e5fc Various fixes to get x86 to compile and work again.
include/dwarf.h: Declare dwarf_reg_state_pool and dwarf_cie_info_pool.
include/dwarf_i.h: Include libunwind_i.h instead of tdep.h.
	Make dwarf_to_unw_regnum() a macro so it doesn't get compiled
	into an object file merely because it include dwarf_i.h (important
	when optimization is turned off).
	(dwarf_read_encoded_pointer_inlined): New function.
include/tdep-x86/libunwind_i.h: Add include of "mempool.h".
include/tdep-x86_64/libunwind_i.h: Add include of "mempool.h".

11ea1275bd [dwarf] The sword() function in Gexpr.c doesn't do what's intended.
Yes, it casts to signed, but then converts right back to
unsigned via the return type.  Fixed thus.

af2503e223 Fix bug in libunwind-ptrace which can cause reading of random data.
(maps_next): After reading less than a full buffer of data, copy
remaining data to the top of the buffer so as to maintain the
invariant that all data between mi->buf and mi->buf_end is valid.
This avoids maps_next() parsing uninitialized data.
