This test was failing with D8 because some test cases relied on DX-specific code
patterns.
This CL moves those test cases to smali and enables D8.

Acts as a partial revert of commit f02c3cf66c2c24533f6da43970e7b766b2ca9938.
Revert only the failing javac/dx checker tests. Update files to match
new checker syntax
(e.g. constant_folding_after_inling -> constant_folding$after_inlining).
Add build scripts to force these tests to use javac/dx even if
the platform build was using jack.
Fixes following tests:
* 442-checker-constant-folding
* 450-checker-types
* 463-checker-boolean-simplifier
* 537-checker-inline-and-unverified

Jack generates different code compared to the previous release so
some tests need to be updated. For instance, Jack transform '!cond'
into 'cond xor 1'.
The test 463-checker-boolean-simplifier still tests the if/else
pattern using smali.

This patch adds a new HIR instruction to Optimizing. HSelect returns
one of two inputs based on the outcome of a condition.
This is only initial implementation which:
- defines the new instruction,
- repurposes BooleanSimplifier to emit it,
- extends InstructionSimplifier to statically resolve it,
- updates existing code and tests accordingly.
Code generators currently emit fallback if/then/else code and will be
updated in follow-up CLs to use platform-specific conditional moves
when possible.

Boolean simplifier should not remove condition instruction
if it has side effects.

In order to prevent tests passing due to lines with hard-to-spot
formatting errors begin ignored, e.g. by forgetting the colon after
"//CHECK", Checker will now require its assertions to start with "///"
or "##", respectivelly for Java and Smali. Such lines will never be
ignored and will fail the test unless successfully parsed.

Checker interprets whitespace as a don't-care placeholder, making it
easier to write assertions which test only parts of the output (e.g.
"//CHECK: Add liveness:44" does not test the inputs or any other
attributes apart from "liveness").
However, since the GraphVisualizer prints lists with elements
separated by spaces ("[ v1 ... vN ]"), this allows for false positives
caused by an occurrence elsewhere in the output. For example, the
assertion: "//CHECK: [ x y ]" will match "[ x y ]" but also
"[ x a y b ]" or even "[ x ] abc [ y ]".
Switching to comma-separated lists works around this issue.
This patch updates all test files, fixes one false positive that this
change revealed (test 442, line 337) and two occurrences of a wrong
match (test 462, lines 121, 149).

This patch changes the syntax for defining and referencing variables
from square brackets '[[VAR]]' to angle brackets '<<VAR>>'. This is
done in order to avoid clashes when matching against lists enclosed
in square brackets.

If statements with negated condition can be simplified by removing the
negation and swapping the true and false branches.

Now that we have the HBooleanNot instruction, the instruction
simplifier can optimize out more conditions comparing a boolean
against a constant, as well as sequences of Boolean negations.

The optimization recognizes the negation pattern generated by 'javac'
and replaces it with a single condition. To this end, boolean values
are now consistently assumed to be represented by an integer.
This is a first optimization which deletes blocks from the HGraph and
does so by replacing the corresponding entries with null. Hence,
existing code can continue indexing the list of blocks with the block
ID, but must check for null when iterating over the list.
