Add a new LiveInterval::overlaps(). It checks if the live interval overlaps a range specified by [Start, End).

for the optimization it's testing to kick in (although
it improves the code, getting rid of all spills).
I don't understand the optimization well enough to
rescue the test, so XFAILing.

my earlier patch to this code only fixed half of it.

Use a safer iterator interface and get rid of std C++ library misuse.
This fixes a --enable-expensive-checks problem.

Regenerate configure.

llvm-svn: 69352

Add a --enable-profiling option to configure to build Debug+Profile and
Opt+Profile tools.  Now we can profile any kind of flavor we build.

copying it to %rdi is not valid.

register is available and when it's profitable.

e.g.
     xorq  %r12<kill>, %r13
     addq  %rax, -184(%rbp)
     addq  %r13, -184(%rbp)
==>
     xorq  %r12<kill>, %r13
     movq  -184(%rbp), %r12
     addq  %rax, %r12
     addq  %r13, %r12
     movq  %r12, -184(%rbp)

Two more instructions, but fewer memory accesses. It can also open up
opportunities for more optimizations.

and argument positions but only to the overloaded intrinsic parameters.
Keep a separate list of these overloaded parameters in CodeGenTarget.cpp
so they can be resolved easily.  Remove assertions from IntrinsicEmitter.cpp:
they were harmless but confusing, and the assertions elsewhere in TableGen
will catch any incorrect values.

locks must be matched with unlocks.  Also, use calloc to allocate the
block so that it is properly zero'd.  Thanks to Nick Kledzik for
tracking this down.

add dependencies on nodes with exactly one successor which is a
COPY_TO_REGCLASS node. In the case that the copy is coalesced
away, the dependence should be on the user of the copy, rather
than the copy itself.

size from the integer, requiring zero extension or truncation. Don't
create ZExtInsts with pointer types. This fixes a regression in
consumer-jpeg.

Do not treat beginning of inlined scope as beginning of normal function scope if the location info is missing.
