Log:
fix PR8102, a case where we'd copyValue from a value that we already
deleted. Fix this by doing the copyValue's before we delete stuff!

Log:
Fix a serious performance regression introduced by r108687 on linux:
turning (fptrunc (sqrt (fpext x))) -> (sqrtf x) is great, but we have
to delete the original sqrt as well. Not doing so causes us to do
two sqrt's when building with -fmath-errno (the default on linux).

fix a bug in my licm rewrite when a load from the promoted memory2010-09-04T00:12:30ZChris Lattnersabre@nondot.org2010-09-04T00:12:30Zurn:sha1:469996400c4ab89d5ddb2eb80acc1c1553439f07

a dangling pointer from the SSAUpdate data structure and miss a
use. This fixes PR8068

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.
