Subject: give StringMap a new ctor which allows you to initialize it
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=a23650bc0161716aadba97e2e5f92eac7c11d80b;p=oota-llvm.git

give StringMap a new ctor which allows you to initialize it
with an existing allocator.  The interesting use case of this
is that it allows "StringMap<whatever, BumpPtrAllocator&>" for
when you want to allocate out of a preexisting bump pointer
allocator owned by someone else.
