[X86][SSE] Transform truncations between vectors of integers into X86ISD::PACKUS/PACKSS operations during DAG combine.

This patch transforms truncation between vectors of integers into
X86ISD::PACKUS/PACKSS operations during DAG combine. We don't do it in
lowering phase because after type legalization, the original truncation

from a vector and then truncated, and from them it is difficult to do
this optimization. This greatly improves the performance of truncations

This is a fairly trivial patch, and should only require a quick review.

I kept the line width smaller than 80 columns, but there are a few exceptions
because I'm not sure how to split a string over several lines.

Xinliang David Li [Sun, 20 Dec 2015 06:22:13 +0000 (06:22 +0000)]
[PGO] Improve Indexed Profile Reader efficiency

With the support of value profiling added, the Indexed prof
reader gets less efficient. The prof reader initialization
used to be just reading the file header, but with VP support
added, initialization needs to walk through all profile keys
of ondisk hash table resulting in very poor locality and large
memory increase (keys are stored together with the profile data
in the mapped profile buffer). Even worse, when the reader is
used by the compiler (not llvm-profdata too), the penalty becomes
very high as compilation of each single module requires touching
profile data buffer for the whole program.

In this patch, the icall target values (MD5hash) are no longer eargerly
converted back to name strings when the data is read into memory. New
interface is added to to profile reader so that InstrProfSymtab can be
lazily created for Indexed profile reader on-demand. Creating of the
symtab is intended to be used by llvm-profdata tool for symbolic dumping
of  VP data. It can be used with compiler (for legacy out of tree uses)
too but not recommended due to compile time and memory reasons
mentioned above.

Some other cleanups are also included: Function Addr to md5 map is now
consolated into InstrProfSymtab. InstrProfStringtab is no longer used and
