Added tinycc test script

[vidyalakshmir]

Added test script to test tinycc.
Total : 9 tests
All tests PASSED.

Tests added :

• Standard Hello World
• Arithmetic Logic
• Floating point
• Argument handling
• Dynamic Memory (malloc/free)
• File I/O
• Bitwise Operations
• Struct Padding and alignment

The tests are created within lindfs/tests/tinycc. They are compiled using lindfs/bin/tcc. The output i386 ELF binary is executed and its output is compared to see if it is expected one.

(Since tcc does not support cross-compilation, many of the original tests cannot be run with tcc.wasm)

Added tests from the tinycc test suite. Around 106 tests were executed. Observations from running the test suite:

• tinycc does not support long double
• Handling large arrays and structs
• Some header files missing (linux/types.h and linux/limits.h)
• out of bounds memory access (tests/tests2/101_cleanup.c)
• tests/tests2/70_floating_point_literals.c

Steps to reproduce
Please run the following from tinycc build PR if it is not merged yet.

cd lind-wasm-apps
make tinycc
make install-tinycc

Then run the tests.
