Change the naming scheme for llvmc plugins so that they do not appear in
'llvm-config --libs' output.

is available; assemble using "llvm-gcc -xassembler"
rather than "as".

I accidentally removed this check in an earlier commit, which cause breakage in the pre alloc splitter.

tells us whether Preprocessor::HandleIdentifier needs to be called.
Because this method is only rarely needed, this saves a call and a
bunch of random checks.  This drops the time in HandleIdentifier 
from 3.52ms to .98ms on cocoa.h on my machine.

Because the RegionStore can reason about values beyond the reasoning power of BasicStore, this patch splits some of the test cases for the retain/release checker to have versions that are handled by RegionStore (more warnings) and BasicStore (less warnings).

Also a few signed comparison fixes.

llvm-svn: 62665

- Ensure that (operation) legalization emits proper FDIV libcall when needed.
- Fix various bugs encountered during llvm-spu-gcc build, along with various
  cleanups.
- Start supporting double precision comparisons for remaining libgcc2 build.
  Discovered interesting DAGCombiner feature, which is currently solved via
  custom lowering (64-bit constants are not legal on CellSPU, but DAGCombiner
  insists on inserting one anyway.)
- Update README.

llvm-svn: 62664

Allow targets to legalize operations (with illegal operands) that produces multiple values. For example, a load with an illegal operand (a load produces two values, a value and chain).

this removes 4266 calls to LookupDecl.

llvm used to generate:
movl    $4294967295, %eax
xorl    4(%esp), %eax

Now it generates:
movl      4(%esp), %eax
notl      %eax

It's 3 bytes shorter.

 - Toolchain is responsible for providing list of prefixes to search.

 - For now forces generation of plist files, need to think about the
   right interface.

 - Changed -fsyntax-only mode to be its own phase (more consistent).

 - Add -WA, for passing options verbatim to analyzer.

Static Analyzer: When generating plists for errors reports, generate one plist file per translation unit that contains all of the diagnostics.

Besides APFloat, this involved removing code
from two places that thought they knew the
result of frem(0., x) but were wrong.
