Now both subtarget define getMaxInlineSizeThreshold and the expansion uses it.

This should not change generated code.

The x86-64 ABI states that objects passed on the stack have
8 byte alignment. Implement that.

* PIC-aware internal structures in X86 Codegen have been refactored
* Visibility (default/weak) has been added
* Docs fixes (external weak linkage, visibility, formatting)

- New target type "mingw" was introduced
- Same things for both mingw & cygwin are marked as "cygming" (as in
gcc)
- .lcomm is supported here, so allow LLVM to use it
- Correctly use underscored versions of setjmp & _longjmp for both mingw
& cygwin

DLL* linkages got full (I hope) codegeneration support in C & both x86
assembler backends.
External weak linkage added for future use, we don't provide any
codegeneration, etc. support for it.

Turns them into calls to memset / memcpy if 1) buffer(s) are not DWORD aligned,
2) size is not known to be greater or equal to some minimum value (currently 128).

* Rename hasSSE -> hasSSE1 to avoid my continual confusion with 'has any SSE'.
* Add inline asm constraint specification.

1. Use SubtargetFeatures in llc/lli.

2. Propagate feature "string" to all targets.

3. Implement use of SubtargetFeatures in PowerPCTargetSubtarget.

Implement the X86 Subtarget.

This consolidates the checks for target triple, and setting options based
on target triple into one place.  This allows us to convert the asm printer
and isel over from being littered with "forDarwin", "forCygwin", etc. into
just having the appropriate flags for each subtarget feature controlling
the code for that feature.

This patch also implements indirect external and weak references in the
X86 pattern isel, for darwin.  Next up is to convert over the asm printers
to use this new interface.
