e5d07538b2 gitignore: Ignore TAGS files 
TAGS files are generated with "make tags" to quickly jump through the
code. Ignore those by-products of automake/ctags.

af7e11de69 build: Add CAIRO_FLAGS to the debugger compilation 
The library in lib/ exposes <cairo.h> in its main header and thus users
must be able to include it.

a5e5d94ce3 Bump gen_level to multiple of tens. 
Add new helper macros to check versions:
- IS_GENp() meant to match Gen X and above
- IS_GENx() meant to match Gen X exactly.

Patch mechanically generated. No stale "gen_level" usage.

b0b540f02a Reduce replicative code in gram.y by reloc_target field in src_operand 
Bspec says JIP and UIP should be the source operands. It is better if
src_operand has a field "reloc_target" according to bspec.
The replicative code in JMPI and branchloop rules can be merged into one.

ccd1721190 Rewrite label matching code. Collect labels in a linked list.

1c009349bc Fix missing environment variables problem in test/run-test.sh 
Currently test/run-test.sh cannot get the value of ${srcdir} and
${top_builddir}. Thus we cannot run any test case. This patch uses
$0 to get the absolute path of run-test.sh. Now test cases work.

5defbd37b6 Pad NOP instructions instead of the ILLEGAL instruction for entry 
If a label is an entry, the assembler will pad empty instruction
before the label until offset % 4 == 0. In the past, the ILLEGAL
instructions are padded. It may raise exceptions. We use the NOP
instructions instead.
