2016-08-30hipe: Reuse liveness info for spillminMagnus Lång
For x86, additionally reuse liveness from float LSRA for the GP LSRA.
2016-08-30hipe_x86: Minimise CFG<->linear conversionsMagnus Lång
Most x86 passes were either linearise(pass(to_cfg(Code))) or trivially rewritable to process a CFG. This saves a great deal of time and memory churn when compiling large programs. Now, there will only ever be a single Linear->CFG conversion, just after lowering from RTL, and only ever a single CFG->Linear conversion, just before the finalise pass. Both of these now happen in hipe_x86_main.
2016-08-30hipe: Fix o0 and o1Magnus Lång
These options would not do anything, because they would not supress the 'o2' in ?COMPILE_DEFAULTS. Such behaviour is added to expand_options/2.
2016-08-30hipe: Add o0 and o1 to testsMagnus Lång
Now that x86 is no longer broken with these optimisation levels, we add them to the test suite to ensure they do not break again. Bump timeout to 6min since tests are run twice as many times. The option set of o1 was changed to all optimisations that run fast on both big and small programs, incurring only a slight compile time increase compared to the old set, but with a, presumably, significant improvement to speed of compiled code. Change o0 register allocator to linear_scan.
2016-08-30hipe_rtl_binary:get_word_integer/4: Handle immsMagnus Lång
Immediate arguments to get_word_integer/4 would lead to bad but unreachable RTL being generated. We omit its generation by testing for immediates and performing the logic at compile time.
2016-08-30hipe_x86: Be resilient to crappy RTLMagnus Lång
The x86 backend crashes if certain RTL optimisations were omitted, preventing it from being usable at lower optimisation levels.
2016-08-30hipe_x86: LSRA for SSE2Magnus Lång
There is little point offering LSRA for x86 if we're still going to call hipe_graph_coloring_regalloc for the floats. In particular, all allocators except LSRA allocates an N^2 interference matrix, making them unusable for really large functions.

2016-08-22hipe: Fix amd64 SSE2 encoding crashMagnus Lång
Register allocation could transform something like fmove u32, d99 to fmove $rdx, 0x20($rsp) which is an invalid instruction.
2016-08-22hipe: Fix tailcall stackarg clobber bugMagnus Lång
Since the link register/return address is restored before stack arguments are stored to the frame, we must not use it to store a stack argument. We do that by adding it to the registers clobbered by pseudo_tailcall_prepare.
2016-08-22hipe_arm: Fix translation of shift by 0Magnus Lång
The problem was caused by shift-by-immediate-zero, which wraps to immediate-32 with some shiftops. TODO: Someplace should be modified to crash when these are generated so debugging further instances of this gets easier in the future.

2016-08-19Reinstate optimization of binary literal matchingBjörn Gustavsson
105c5b0071 was reverted in dd1162846e because clauses that were supposed to match would not match. (See 8b83bc0b.) Reintroduce the optimization, but make sure that we only shortcut bs_context_to_binary instructions and not bs_start_match2 instructions.

Don't only test the case that failed; test it exhaustively.
