According to the code in httpc.erl, the pquery parameter in the
#request record should start with a question mark. However, when
a server returned a 403 response, the Location header was parsed
and the question mark was not added to the beginning of the query
string. This ultimately causes the redirect to fail, as instead of
redirecting to "/path?query", httpc redirected to "/pathquery".

Add support of non-whole-byte binaries to `abtract/1`, `concrete/1` and
`is_literal/1`. (They are literals in the beam file)

The compiler would crash when compiling code such as:
serialize(#{tag := value, id := Id, domain := Domain}) ->
[case Id of
nil ->
error(id({required, id}));
_ ->
<<10, 1:16/signed, Id:16/signed>>
end,
case Domain of
nil ->
error(id({required, domain}));
_ ->
<<8, 2:16/signed, Domain:32/signed>>
end].
The crash would look like this:
Function: serialize/1
t.erl: internal error in block2;
crash reason: {badmatch,false}
in function beam_utils:live_opt/4 (beam_utils.erl, line 861)
in call from beam_utils:live_opt/1 (beam_utils.erl, line 285)
in call from beam_block:function/2 (beam_block.erl, line 47)
in call from beam_block:'-module/2-lc$^0/1-0-'/2 (beam_block.erl, line 33)
in call from beam_block:'-module/2-lc$^0/1-0-'/2 (beam_block.erl, line 33)
in call from beam_block:module/2 (beam_block.erl, line 33)
in call from compile:block2/2 (compile.erl, line 1358)
in call from compile:'-internal_comp/5-anonymous-1-'/3 (compile.erl, line 349)
The reason for the crash is an assertion failure caused by a previous
unsafe optimization. Here is the code before the unsafe optimization:
.
.
.
{bs_init2,{f,0},7,0,0,{field_flags,[]},{x,1}}.
{bs_put_string,3,{string,[8,0,2]}}.
{bs_put_integer,{f,0},{integer,32},1,{field_flags,[signed,big]},{y,1}}.
{move,{x,1},{x,0}}.
{test_heap,4,1}.
.
.
.
beam_block:move_allocate/1 moved up the test_heap/2 instruction past the
move/2 instruction, adjusting the number of live registers at the same
time:
.
.
.
{bs_init2,{f,0},7,0,0,{field_flags,[]},{x,1}}.
%% Only x1 is live now.
{bs_put_string,3,{string,[8,0,2]}}.
{bs_put_integer,{f,0},{integer,32},1,{field_flags,[signed,big]},{y,1}}.
{test_heap,4,2}. %Unsafe. x0 is dead.
{move,{x,1},{x,0}}.
.
.
.
This optimization is unsafe because the bs_init2 instruction killed
x0.
The bug is in beam_utils:anno_defs/1, which adds annotations indicating
the registers that are defined at the beginning of each block. The
annotation before the move/2 instruction incorrectly indicated that
x0 was live.

With DEBUG=true in erl_anno, erl_parse, and erl_pp a few (harmless)
non-opaque accesses of annotations were found.
