Adding option to llc for ModuloScheduling. By default it is turned off.

Update comments, now that CPR's are gone, inline the methods

Check in hook that I forgot

Fix PR456:\
Tools and libraries will be built into $(BUILD_OBJ_ROOT)/$(BuildMode)/bin and \
$(BUILD_OBJ_ROOT)/$(BuildMode)/lib, respectively. Furthermore, the example \
programs will go in $(BUILD_OBJ_ROOT)/$(BuildMode)/examples to keep them \
separate from the tools and hopefully out of the PATH. Install targets \
have not changed.

Include ltdl.h if we have it.

Add checks for HAVE_LTDL_H and HAVE_LT_DLOPEN

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17951 91177308-0d34-0410-b5e6-96231b3b80d8

Changes for testing presence of ltdl.h and lt_dlopen(), libtool functions
for cross-platform dynamic loading of shared objects.

Rewrite LoadArgumentsToVirtualRegs, making it match almost exactly how
visitCallInst works.  Support cast of byte/short/int to long.

Update current expected failures list - expand it to include all of
SingleSource. Update to-do list (open-coding refers to binary operations on
longs, not to passing them into functions, which we already support.)

Eliminate another common source of moves that the register allocator
shouldn't be forced to coalesce for us: folded GEP operations.  This too
fires thousands of times across the testsuite.

When accessing the base register for global variables, use the register
directly rather than making a copy for the register allocator to coalesce.
This kills thousands of live intervals across the testsuite.
