Some tools (eg ccls) require that the compiler in argv[0] of the
compdb be an actual compiler binary. Until now we had simply filled
that slot with /bin/false. This change fills it with the current
default clang binary instead.
Test: make -j50 SOONG_GEN_COMPDB=1 SOONG_GEN_COMPDB_DEBUG=1 SOONG_LINK_COMPDB_TO=$ANDROID_BUILD_TOP nothing
Test: Use ccls

compdb.go was incorrectly splitting compiler arguments. This could
cause empty strings to be included in compile_commands.json,
potentially confusing tools.

Test: m checkbuild
Test: m SOONG_GEN_COMPDB=1 \
SOONG_GEN_COMPDB_DEBUG=1 \
SOONG_LINK_COMPDB_TO=$ANDROID_BUILD_TOP nothing
Examine $ANDROID_BUILD_TOP/compile_commands.json

Some tools (i.e. you-complete-me) make use of a 'compdb' file
(compile_commands.json) that records (among other things) the
arguments needed to compile a file. These tools can use this with
libclang to provide semantic completions and perform other IDE
actions. This CL adds support for soong to generate a (simple)
compile_commands.json file.
Test: make SOONG_GEN_COMPDB=1 SOONG_LINK_COMPDB_TO=$ANDROID_BUILD_TOP nothing
examine $ANDROID_BUILD_TOP/compile_commands.json
