484a96fab1 Add ImmutableMapRef and ImmutableSetRef, which consolidate Immutable[Map,Set] and its Factory. This may eventually replace Immtuable[Map,Set].

396b8136bf Add mayLoad attribute to AVX convert instructions, since non of them 
are declared with load patterns. This fix the crash in PR10941. No testcases,
since a fold is triggered and then converted back to the register form
afterwards.

a60e62ad02 Fix PR10884. 
This PR basically reports a problem where a crash in generated code
happened due to %rbp being clobbered:

  pushq %rbp
  movq  %rsp, %rbp
  ....
  vmovmskps %ymm12, %ebp
  ....
  movq  %rbp, %rsp
  popq  %rbp
  ret

Since Eric's r123367 commit, the default stack alignment for x86 32-bit
has changed to be 16-bytes. Since then, the MaxStackAlignmentHeuristicPass
hasn't been really used, but with AVX it becomes useful again, since per
ABI compliance we don't always align the stack to 256-bit, but only when
there are 256-bit incoming arguments.

ReserveFP was only used by this pass, but there's no RA target hook that
uses getReserveFP() to check for the presence of FP (since nothing was
triggering the pass to run, the uses of getReserveFP() were removed
through time without being noticed). Change this pass to use
setForceFramePointer, which is properly called by MachineFunction
hasFP method.

The testcase is very big and dependent on RA, not sure if it's worth
adding to test/CodeGen/X86.

381ec749e0 Move the AC_PROG_CC checks earlier in the configure file. The lateness 
of the original check meant that configure was caching the default
CC check and using that instead of the result of AC_PROG_CC in both
configure checks and during compilation.

This wasn't affecting C++ so it was hard to notice.

Regenerate configure.

3163b0a2ce We now look for clang, then llvm-gcc, then gcc as our compiler. We don't need 
this anymore.
