2b0edc3327 PR4286: Make RewriteLoadUserOfWholeAlloca and 
RewriteStoreUserOfWholeAlloca deal with tail padding because 
isSafeUseOfBitCastedAllocation expects them to.  Otherwise, we crash 
trying to erase the bitcast.

4a228edc3a Add a DEBUG() output to GVN that prints the instruction clobbering a load. 
This is useful when trying to figure out why GVN didn't eliminate redundant
loads.

dd6cbdb28c The MONITOR and MWAIT instructions have insufficient information for 
decoding. Essentially, they both map to the same column in the "opcode
extensions for one- and two-byte opcodes" table in the x86 manual. The RawFrm
complicates decoding this.

Instead, use opcode 0x01, prefix 0x01, and form MRM1r. Then have the code
emitter special case these, a la [SML]FENCE.

bf3a09e3ee NightlyTest: Write "sentdata.txt" files and run the -submit-aux script before 
sending data to the server.
 - Otherwise if the server connection fails the external script never runs.

Also, create content before initiating connection to try and decrease time we
are connected to llvm.org.
