Comment (by thoughtpolice):

 @Simon, I've tried sprinkling some `NOINLINE` to see if it has any effect
 on pressure the codegen might be under - indeed, if I sprinkle a few
 `NOINLINE` here and there like on `genCCall` (a massive piece of code in
 its own right), then `System.Time` does compile, but DPH fails to compile
 later on:

 {{{
 libraries/dph/dph-lifted-vseg/ghc.mk:5: recipe for target 'libraries/dph
 /dph-lifted-vseg/dist-
 install/build/Data/Array/Parallel/PArray/PData/Base.p_o' failed
 make[1]: *** [libraries/dph/dph-lifted-vseg/dist-
 install/build/Data/Array/Parallel/PArray/PData/Base.p_o] Segmentation
 fault
 }}}

 I'm checking if this is the same thing as before right now.

 I will note that in the example I posted in the other comment, `a292_rFAj`
 at the STG level - which roughly corresponds to `stmtToInstrs` - is
 ''absolutely massive'' - by itself, it's on the order of 24,000 lines of
 intermediate code long. `X86.CodeGen` really only exports `cmmTopCodeGen`,
 so it probably goes to town on the module, inlining like crazy, since
 `stmtToInstrs` is at the heart of it.
