[compiler-rt] Allow trampoline allocation further and 1 gig.
Summary:
The trampoline allocation limits the memory scanning to 1 gig.
There is an unittest that is allocating a large object which make
it impossible to the trampoline allocator to find a free spot.
see shadow_mapping_failures:
```
char bigchunk[1 << 30];
```
This patch is not fixing the unittest but it's fixing it's infinite
loop behavior.
