Fix mismatched type problem that crashed on cases like this:

  sprintf(P, "%s", X);

Where X is not an sbyte*.  This fixes the bug JohnMC reported on llvm-bugs.

New testcase that crashes simplifycfg, identified accidentally by JohnMC

C'mon everybody, let's modify X86JITInfo.cpp.  This time, we add <iostream>
so that the shiny new use of std::cerr is defined.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22156 91177308-0d34-0410-b5e6-96231b3b80d8

Finally get the quoting right for both Unix and Windows for the llvmgcc and
llvmgxx programs. dejagnu doesn't understand single quote and we need to
pass double quotes through to the shell in order to escape blanks in the
paths. This patch uses \" to escape the quotes passed through to the shell.
Thanks to Aaron Gray for testing this out on cygwin.

Two changes to support building shared libraries that contain multiple
llvm archive or re-linked libraries:
1. Permit the "JIT" special keyword on LLVMLIBS to be recognized when
   building a library, not just for building tools
2. If LINK_LIBS_IN_SHARED is set, the LLVMLIBS and USEDLIBS can be specified
   when linking a shared library and the libraries listed will be
   incorported into the shared library. THis is only used when the
   SHARED_LIBRARY variable is set.

don't reserve space for tailcall arg areas.  It explicitly managed.

Make note of the -simplify-libcalls pass.

add test to check for tail calls

Teach reginfo how to deal with ADJSTACKPTRri, allowing us to generate:
        add %ESP, 20
        jmp %EDX  # TAIL CALL

instead of:
        add %ESP, -8
        add %ESP, 28
        jmp %EDX  # TAIL CALL

Implement proper tail calls in the X86 backend for all fastcc->fastcc
tail calls.

Substantial edits for the release notes.

Add some simplifications for MULH[SU].  This allows us to compile this:

long %bar(long %X) {
  %Y = mul long %X, 4294967297
  ret long %Y
}

to this:

l1_bar:
        mov %EAX, DWORD PTR [%ESP + 4]
        mov %EDX, %EAX
        add %EDX, DWORD PTR [%ESP + 8]
        ret

instead of:

l1_bar:
        mov %ECX, DWORD PTR [%ESP + 4]
        mov %EDX, 1
        mov %EAX, %ECX
        mul %EDX
        add %EDX, %ECX
        add %EDX, DWORD PTR [%ESP + 8]
        mov %EAX, %ECX
        ret

Add markers in the asm file for tail calls, add a new ADJSTACKPTRri
sorta-pseudo-instruction

When inserting callee-save register reloads, make sure to skip over any
terminator instructions before the 'ret' in case the target has a
multi-instruction return sequence.

Yes, calltarget is the operand of the day.

Make sure this is not eligible for tail-call-elimination so that we test
the correct thing.

When emitting the function epilog, check to see if there already a stack
adjustment.  If so, we merge the adjustment into the existing one.  This
allows us to generate:

caller2:
        sub %ESP, 12
        mov DWORD PTR [%ESP], 0
        mov %EAX, 1234567890
        mov %EDX, 0
        call func2
        add %ESP, 8
        ret 4

intead of:

caller2:
        sub %ESP, 12
        mov DWORD PTR [%ESP], 0
        mov %EAX, 1234567890
        mov %EDX, 0
        call func2
        sub %ESP, 4
        add %ESP, 12
        ret 4

Forgot to commit this earlier. Its part of the simplify-libcalls
enhancement for ffs, ffsl, and ffsll optimizations. We can't do the opt
unless we also have the at least ffsll function. Notably SVR4 doesn't.
