Fix an infinite loop; merging two functions will create a new function (if the2010-08-31T08:29:37ZNick Lewyckynicholas@mxc.ca2010-08-31T08:29:37Zurn:sha1:65a0af3855c7003fa57d41eeb6586b20eefa8cfd
two are weak, we make them thunks to a new strong function) so don't iterate
through the function list as we're modifying it.
Also add back the outermost loop which got removed during the cleanups.

where we hash, compare and fold, instead of one iteration where we build up
the hash buckets and a second one to fold.

Reapply r112091 and r111922, support for metadata linking, with a2010-08-26T15:41:53ZDan Gohmangohman@apple.com2010-08-26T15:41:53Zurn:sha1:6cb8c23db1c3becdce6dfbf1b7f1677faca4251e
fix: add a flag to MapValue and friends which indicates whether
any module-level mappings are being made. In the common case of
inlining, no module-level mappings are needed, so MapValue doesn't
need to examine non-function-local metadata, which can be very
expensive in the case of a large module with really deep metadata
(e.g. a large C++ program compiled with -g).
This flag is a little awkward; perhaps eventually it can be moved
into the ClonedCodeInfo class.
