a7b306188b Executables will be at InstallDir/bin directory. Std header files will be at InstallDir/include, libs will be at InstallDir/lib. Define hooks for these and use them in the options for various tools.

65ed3d6ce7 NewNightlyTest: Include minutes/seconds in log file names, to support running 
multiple runs per day (insane, I know).

Also, remove some unused variables.

e6989735a6 CommuteChangesDestination() should check if to-be-commuted instruction defines any register. Also teaches the default commuteInstruction() to commute instruction without definitions (e.g. X86::test / ARM::tsp).

7d78cb531e Remove special handling of implicit_def. Fix a couple more bugs in liveintervalanalysis and coalescer handling of implicit_def. 
Note, isUndef marker must be placed even on implicit_def def operand or else the scavenger will not ignore it. This is necessary because -O0 path does not use liveintervalanalysis, it treats implicit_def just like any other def.

37503e9671 Handle IMPLICIT_DEF with isUndef operand marker, part 2. This patch moves the code to annotate machineoperands to LiveIntervalAnalysis. It also add markers for implicit_def that define physical registers. The rest, is just a lot of details.

bc3d149e98 Remove unused AsmPrinter OptLevel argument, and propogate. 
- This more or less amounts to a revert of r65379. I'm curious to know what
   happened that caused this variable to become unused.

d0589c59b3 llvm-mc: Symbols in a relocatable expression of the (a - b + cst) form are 
allowed to be undefined when the expression is seen, we cannot enforce the
same-section requirement until the entire assembly file has been seen.

c0fb316bd3 Add an "alignment" field to the MachineFunction object. It makes more sense to 
have the alignment be calculated up front, and have the back-ends obey whatever
alignment is decided upon.

This allows for future work that would allow for precise no-op placement and the
like.

340632e814 Fix PR4485. 
Avoid unnecessary duplication of operand 0 of X86::FpSET_ST0_80. This duplication would
cause one register to remain on the stack at the function return.
