	PR go/52583
runtime: Stop backtrace at a few recognized functions.

On x86_64 Solaris the makecontext function does not properly
indicate that it is at the top of the stack.  Attempting to
unwind the stack past a call to makecontext tends to crash.
This patch changes libgo to look for certain functions that
are always found at the top of the stack, and to stop
unwinding when it reaches one of those functions.  There is
never anything interesting past these functions--that is,
there is never any code written by the user.

From-SVN: r211640

	PR go/61498
runtime: Always set gcnext_sp to pointer-aligned address.

The gcnext_sp field is only used on systems that do not use
split stacks.  It marks the bottom of the stack for the
garbage collector.  This change makes sure that the stack
bottom is always aligned to a pointer value.

Previously the garbage collector would align all the addresses
that it scanned, but it now expects them to be aligned before
scanning.
