Reapply commit 112699, speculatively reverted by echristo, since2010-09-02T08:14:03ZDuncan Sandsbaldrick@free.fr2010-09-02T08:14:03Zurn:sha1:fc6e29d4ab52b7d3efd83846ed495a9ca7e51e49
I'm sure it is harmless. Original commit message:
If PrototypeValue is erased in the middle of using the SSAUpdator
then the SSAUpdator may access freed memory. Instead, simply pass
in the type and name explicitly, which is all that was used anyway.

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.
