_FastMallocBuffer with gc=yes

[James Knight]

FastMallocBuffer should not be used when GC is enabled. Not only is it 
not necessary, right now it causes problems, as it directly calls into 
the autorelease pool, which, itself, is not used in GC applications, and 
should not be called. The attached patch makes _FastMallocBuffer(size) 
simply call GC_malloc(size) with GC enabled.

(this patch is against gnustep-base-1.3.2)
