df2e425f2a Add a new option to indicate we want the code generator to emit code quickly,
not spending tons of time microoptimizing it.  This is useful for an -O0
style of build.

5ab8363206 Since getSubtarget() always provides a const Subtarget, dont' require the user
to pass it in.  Also, since it always returns a non-null pointer, make it
return a reference instead for easier use.

fb5792f416 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.

36c2a05935 Delete the V9 specific findOptimalStorageSize method, inlining it into all callers.
Substantially clean up all target implementations by having the OPTIONAL get*Info
methods return a pointer instead of a reference.  This allows us to have default
implementations!

05b15fb075 TargetCacheInfo has been removed; its only uses were to propagate a constant
(16) into certain areas of the SPARC V9 back-end. I'm fairly sure the US IIIi's
dcache has 32-byte lines, so I'm not sure where the 16 came from. However, in
the interest of not breaking things any more than they already are, I'm going
to leave the constant alone.
