Chris Lattner 3e96211bc8 Fix codegen for x86-64 on systems (like ppc or i386) that don't have 64-bit 
features autodetected.  This fixes PR1010 and Regression/CodeGen/X86/xmm-r64.ll
on non-x86-64 hosts.

Evan Cheng 9274f72e58 Do away with CPU feature list. Just use CPUID to detect MMX, SSE, SSE2, SSE3, and 64-bit support.

Evan Cheng 4c1a804a5b It appears the inline asm in GetCpuIDAndInfo() may clobbers some registers if it isn't inlined (at < -O3). Force it to be inlined.

Chris Lattner b9e0a9e82f Fix a cross-build issue. The asmsyntax shouldn't be affected by the build 
host, it should be affected by the target.  Allow the command line option to
override in either case.

Evan Cheng 03c1e6f48e A bit more memset / memcpy optimization. 
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).

Nate Begeman f26625e1de Implement Subtarget support 
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.
