Enable support for vector sext and trunc:2011-02-24T21:01:34ZNadav Rotemnadav.rotem@intel.com2011-02-24T21:01:34Zurn:sha1:8c20ec54d98176d31f310e4684d1d7f2ea0639bc
Limit the folding of any_ext and sext into the load operation to scalars.
Limit the active-bits trunc optimization to scalars.
Document vector trunc and vector sext in LangRef.
Similar to commit 126080 (for enabling zext).

Fix 9267; Add vector zext support.2011-02-20T12:37:50ZNadav Rotemnadav.rotem@intel.com2011-02-20T12:37:50Zurn:sha1:ed9b934f65d82324506f03e2db2834682c7a8914
The DAGCombiner folds the zext into complex load instructions. This patch
prevents this optimization on vectors since none of the supported targets
knows how to perform load+vector_zext in one instruction.

First step in fixing PR8927:2011-01-08T16:42:36ZRafael Espindolarafael.espindola@gmail.com2011-01-08T16:42:36Zurn:sha1:bea4626f93c830e31f82cc947df28fdae583cd09
Add a unnamed_addr bit to global variables and functions. This will be used
to indicate that the address is not significant and therefore the constant
or function can be merged with others.
If an optimization pass can show that an address is not used, it can set this.
Examples of things that can have this set by the FE are globals created to
hold string literals and C++ constructors.
Adding unnamed_addr to a non-const global should have no effect unless
an optimization can transform that global into a constant.
Aliases are not allowed to have unnamed_addr since I couldn't figure
out any use for it.
