ed4f1f4c43 hotfix 3221ac0943 broke gc:regions/aka gc:stack by 
underallocating for sequences of any type larger than 1 byte.  This does the
necessary multiply to restore basic functionality.

9f943dbc8e Don't zeroMem result of boehmAlloc() (#7029) 
From the man page: "Unlike the standard implementations of malloc, GC_malloc
clears the newly allocated storage. GC_malloc_atomic does not."

__go_free() was removed from gcc-7.2.0 so we stop trying to help the
garbage collector by marking no longer used memory regions

250375bdd2 Remove spurious unsigned operations from system/threads.nim. 
These operations were included before the unsigned module was
incorporated directly into system.nim and subsequently caused
compilation errors with --gc:go due to duplicate definitions.

639b5e0069 Properly register threads with the Boehm GC. 
In order to be able to scan thread stacks, the Boehm GC needs to know
about newly created threads. We establish the end of the stack by using
GC_call_with_stack_base (this works properly also with the dual-stack
Itanium architecture) and then GC_register_my_thread() to register a
thrad and GC_unregister_my_thread() to unregister it again.

This patch also includes a modification for the refc and markandsweep
collectors to set the stack bottom for thread stacks correctly even if
an optimizer aggressively inlines and optimizes procedures (this is
already being done for the stack of the main thread).

Finally, we use the {.noconv.} pragma for the Boehm GC, as the Boehm
API uses no specific calling convention.

1001fd2166 Fix Boehm GC on linux 
Motivation
----------
Some linuxes (like Fedora) actually multiarch. And it means that
libgc.so.1 not always installed into /usr/lib. It is better to entrust
this job to ld and system configuration for it.

Modification
------------
Use relative path for Boehm GC on 'other' OS (and linux in particular)

Result
------
It is possible now to build nim with --gc:boehm on linux

b11493585c Various fixes to how the Boehm GC's interface. 
The Boehm GC interface did not define the getXXXSharedMem() functions
that were needed for compilation with --threads:on. It also used
`ppointer` instead of `PPointer`, so it failed to compile with
--cs:partial.
